Question

C.Find the value of a, b, and c and determine the sum and the product of the roots of each quadratic equation.

Use the formula: sum: -b/a ; product: c/a

1. x² + 9x + 20=0

2. 2x² + 10x + 6=0

help...​

Answer 1

Step-by-step explanation:

1. x2 + 9x + 20 = 0

comparing with ax2 + bx + c = 0

a=1 ,b= 9 ,c=20

sum = -9/1 = -9

product = 20/1 = 20

2. 2x2 + 10x + 6 = 0

comparing with ax2 + bx + c = 0

a= 2,b= 10 , c= 6

sum = 10/2 = 5

product = 6/2 = 3
