Question

hleppppp plllzz find the roots of the function x^2-10x+16=0

a,x=4,4
b,x=2,4
c,x=-2,8
d,x=-2,-8

Answer 1

x^2 - 10x + 16 = 0
x^2 - 8x - 2x + 8*2 = 0
x(x-8) - 2(x-8) = 0
(x - 8)(x - 2) = 0

x - 8 = 0
x - 2 = 0

x = 8
x = 2

Answer 2

Again, answer choices don't match

Answer 3

it wz b,x=2,8 i ve some kind of problem with copying down lol

Answer 4
