Question

OR
Find product and sum of zeroes of polynomial 2x2 - 5x + 7.​

Answer 1

Answer:

2×2-5x+7

4-5x+7

4-5x=-7

-5x=-7-4

-5x=-11

x=-11/-5

Answer 2

Given,

A quadratic equation 2x²-5x+7 = 0

To Find,

The sum and product of zeroes of this equation.

Solution,

The formula for calculating the sum and product of zeroes is

Sum of zeroes = -b/a

where b is the coefficient of x and a is the coefficient of x².

Product of zeroes = c/a

where c is the constant

So,

Sum of zeroes = 5/2

Product of zeroes = 7/2

Hence, the sum of zeroes is 5/2 and the product of zeroes is 7/2.
