1. This algebraic expression can be factored by identifying the perfect square components. The first part of the expression is 49g square, which is equal to (7g) square. The last part is h square, which is equal to (h) square. The middle value 14gh is exactly two times 7g times h. Since it matches theRead more

    This algebraic expression can be factored by identifying the perfect square components. The first part of the expression is 49g square, which is equal to (7g) square. The last part is h square, which is equal to (h) square. The middle value 14gh is exactly two times 7g times h. Since it matches the standard addition identity completely, it condenses into the final perfect square binomial factor (7g + h) square.

  2. To factor this long polynomial, we examine the perfect square bases which are 8u, 11v and 2w. We observe that the cross-product terms 176uv and 32uw are negative, while 44vw is positive. Because the product of v and w becomes positive while their separate combinations with u are negative, both the 1Read more

    To factor this long polynomial, we examine the perfect square bases which are 8u, 11v and 2w. We observe that the cross-product terms 176uv and 32uw are negative, while 44vw is positive. Because the product of v and w becomes positive while their separate combinations with u are negative, both the 11v and 2w bases must carry negative signs. This produces the complete factored solution (8u – 11v – 2w) square.

  3. In a standard square root spiral, the first right triangle has perpendicular sides of length 1 unit each. By the Pythagorean theorem, its hypotenuse is the square root of 2. The next right triangle is built using this hypotenuse as a base and adding a perpendicular side of 1 unit, making its hypotenRead more

    In a standard square root spiral, the first right triangle has perpendicular sides of length 1 unit each. By the Pythagorean theorem, its hypotenuse is the square root of 2. The next right triangle is built using this hypotenuse as a base and adding a perpendicular side of 1 unit, making its hypotenuse the square root of 3. This mathematical pattern continues sequentially for all successive right triangles, creating hypotenuse lengths of root 2, root 3, root 4, root 5, and so on.

  4. We are given two equations: x + y + z = 0 and xy + yz + zx = 0. Using the algebraic identity, we know that (x + y + z) squared equals x2 + y2 + z2 + 2(xy + yz + zx). Substituting our given values into this identity results in 0 squared equals x2 + y2 + z2 + 2(0), which simplifies directly to x2 + y2Read more

    We are given two equations: x + y + z = 0 and xy + yz + zx = 0. Using the algebraic identity, we know that (x + y + z) squared equals x2 + y2 + z2 + 2(xy + yz + zx). Substituting our given values into this identity results in 0 squared equals x2 + y2 + z2 + 2(0), which simplifies directly to x2 + y2 + z2 = 0. Since the square of any real rational number is always non-negative, their sum can only equal zero if x, y, and z are all simultaneously zero.

  5. The denominator of the rational number in its lowest form is given as 2 cubed times 5, which equals 8 times 5, or 40. A fraction with a denominator of the form 2 raised to m times 5 raised to n will always have a terminating decimal expansion. The number of decimal places is determined by the higherRead more

    The denominator of the rational number in its lowest form is given as 2 cubed times 5, which equals 8 times 5, or 40. A fraction with a denominator of the form 2 raised to m times 5 raised to n will always have a terminating decimal expansion. The number of decimal places is determined by the higher exponent of the prime factors 2 and 5. Since the exponent of 2 is 3, it will have exactly 3 decimal places.
