4u² + 8u = 4u² +8u = 4u(u + 2) The value of 4u² + 8u is zero if 4u = 0 or u + 2 = 0. ⇒ u = 0 or u = -2. Therefore, the zeroes of 4u² + 8u are 0 and -2. Now, Sum of zeroes = 0 + (-2) = -2 = -(8)/4 = -(Coficient of u)/Cofficient of u²) Product of zeroes = 0 x (-2) = 0 = 0/4 = (Constant term)/(CofficieRead more
4u² + 8u
= 4u² +8u
= 4u(u + 2)
The value of 4u² + 8u is zero if 4u = 0 or u + 2 = 0.
⇒ u = 0 or u = -2.
Therefore, the zeroes of 4u² + 8u are 0 and -2.
Now, Sum of zeroes = 0 + (-2) = -2 = -(8)/4 = -(Coficient of u)/Cofficient of u²)
Product of zeroes = 0 x (-2) = 0 = 0/4 = (Constant term)/(Cofficient of u²)

The study of polynomials can be beneficial to students by helping them develop important mathematical skills, understand real-world applications, prepare them for further study, and improve their problem-solving skills.
t² - 15 = t² - (√15)² = (t + √15)(t - √15) The value of t² - 15 is zero if t + √15 = 0 or t - √15 = 0. ⇒ x = - √15 or x = √15. Therefore, the zeroes of t² - 15 are - √15 and √15. Now, Sum of zeroes = -√15 + √15 = 0 = -(0)/1 = -(Cofficient of t)/(Cofficient of t²) Product of zeroes = (-√15) x √15 = -Read more
t² – 15
= t² – (√15)²
= (t + √15)(t – √15)
The value of t² – 15 is zero if t + √15 = 0 or t – √15 = 0.
⇒ x = – √15 or x = √15.
Therefore, the zeroes of t² – 15 are – √15 and √15.
Now, Sum of zeroes = -√15 + √15 = 0 = -(0)/1 = -(Cofficient of t)/(Cofficient of t²)
Product of zeroes = (-√15) x √15 = -15 = -15/1 (Constant term)/(Cofticient of t²)
Resources can be classified based on their origin, which refers to where they come from or how they are obtained. Some common categories of resources based on their origin include: Natural resources: These are resources that are found in nature and are not originated by humans. Examples include mineRead more
Resources can be classified based on their origin, which refers to where they come from or how they are obtained. Some common categories of resources based on their origin include:
Natural resources: These are resources that are found in nature and are not originated by humans. Examples include minerals, timber, water, and air.
Man-made resources: These are resources that are originated by humans using raw materials or other resources. Examples include manufactured goods, such as cars, computers, and appliances.
Renewable resources: These are resources that can be replenished naturally over time. Examples include solar energy, wind energy, and hydroelectric power.
Nonrenewable resources: These are resources that are finite and cannot be replaced once they are used up. Examples include fossil fuels (such as coal, oil, and natural gas) and minerals.
