Question

The roots of the quadratic equation x 2 - 8x + 15 = 0 are
1 point
2,3
3,5
8,15
3,-15

Answer 1

Hey there,

By Splitting the middle term

x^2-3x-5x+15=0

x(x-3)-5(x-3)=0

(x-3)(x-5)=0

Thus the values of x that satisfy the equation are 3 and 5.

Answer 2

Answer:

a=1 b= -8 C= 15

a x c= 15

take x common :-

x(x-8)+1(x-8)

so there factors are:-

(x+1)(x-8)
