Question

Find the sum and product of the zeroes of the quadratic polynomial 4x+7x+8

Answer 1

Answer:  quadratic polynomial 4x²+7x+8

To Find : sum and product of the zeroes

Solution:

ax² + bx + c

Sum of Zeroes =  - b/a

Product of Zeroes = c/a

4x²+7x+8

a = 4    b = 7  c = 8

Sum of Zeroes =  -7/4

Product of Zeroes = 8/4 = 2

Sum of Zeroes =  -7/4

Product of Zeroes = 2

Answer 2

Given: The correct equation is 4x²+7x+8

To find: The sum and product of the zeroes.

Solution:

• Now we have provided with the equation: 4x²+7x+8

• The standard equation is: ax² + bx + c

• Here a = 4, b = 7 and c = 8.

• Now sum of roots is : -b/a = -7/4

• Product of roots is : c/a = 8/4 = 2/1

Answer:

          So the sum of roots is -7/4 and product of roots is 2
