    Let α and β are the zeroes of the polynomial ax² + bx + c, then we have α + β = √2 = (3√2)/3 = (-b)/a αβ = 1/3 = c/a On comparing, a = 3, b =-3/√2 and c = 1 Hence, the required quadratic polynomial is 3x² - 3/√2 + 1.

    Let α and β are the zeroes of the polynomial ax² + bx + c, then we have
    α + β = √2 = (3√2)/3 = (-b)/a
    αβ = 1/3 = c/a
    On comparing,
    a = 3, b =-3/√2 and c = 1
    Hence, the required quadratic polynomial is 3x² – 3/√2 + 1.

    Video Explanation 😃

    Understanding polynomials is essential for further study in mathematics, including topics such as algebra and calculus. Studying polynomials helps students develop important mathematical skills, such as algebraic manipulation, problem-solving, and critical thinking.

    Let α and β are the zeroes of the polynomial ax² + bx + c, then we have α + β = 1 = 1/1 = (-b)/a αβ = 1 = 1/1 c/a On comparing, a = 1, b = -1 and c = 1 Hence, the required quadratic polynomial is x² - x + 1. Explanation 👇

    Let α and β are the zeroes of the polynomial ax² + bx + c, then we have
    α + β = 1 = 1/1 = (-b)/a
    αβ = 1 = 1/1 c/a
    On comparing,
    a = 1, b = -1 and c = 1
    Hence, the required quadratic polynomial is x² – x + 1.

    Let α and β are the zeroes of the polynomial ax² + bx + c, then we have α + β = 1/4 = (-b)/a αβ = -1 = (-4)/4 = c/a On comparing, a = 4, b = -1 and c = -4 Hence, the required quadratic polynomial is 4x² - x - 4. See here 👇

    Let α and β are the zeroes of the polynomial ax² + bx + c, then we have
    α + β = 1/4 = (-b)/a
    αβ = -1 = (-4)/4 = c/a
    On comparing,
    a = 4, b = -1 and c = -4
    Hence, the required quadratic polynomial is 4x² – x – 4.

  5. Asked: December 27, 2020In: Class 10 Maths

    Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients. 3x² – x – 4.

    3x² - x - 4 = 3x² - 4x + 3x - 4 = x(3x - 4) + 1(3x - 4) = (3x - 4)(x + 1) The value of 3x² - x - 4 is zero if 3x - 4 0 or x + 1 0. ⇒ x = 4/3 or x = -1. Therefore, the zeroes of 3x² - x - 4 are and -1. Now, Sum of zeroes = 4/3 +(-1) = (4 - 3)/3 = 1/3 = -(-1)/3 = -(Coficient of x)/(Cofficient of x²) PRead more

    3x² – x – 4
    = 3x² – 4x + 3x – 4
    = x(3x – 4) + 1(3x – 4)
    = (3x – 4)(x + 1)
    The value of 3x² – x – 4 is zero if 3x – 4 0 or x + 1 0.
    ⇒ x = 4/3 or x = -1.
    Therefore, the zeroes of 3x² – x – 4 are and -1.
    Now, Sum of zeroes = 4/3 +(-1) = (4 – 3)/3 = 1/3 = -(-1)/3 = -(Coficient of x)/(Cofficient of x²)
    Product of zeroes = 4/3 × (-1) = -4/3 = (-4)/3 = (Coefficient of term)/(Cofficient of x²)
