2x2 +12x=32
2x2+12x-32=0 ( 232=64, 164=64.)
2x2 + 16x-4x-32=0
2x2-4x+16x-32=0
2x(x-2) +16(x-2)=0
(2x+16)(x-2)=0
x=-16/2 or x=2
{x=-8,2}
Answer:
2(x - 2)(x + 8)
x = 2, x = -8
Step-by-step explanation:
Hello!
Set the given equation to standard form \(ax^2 + bx + c = 0\):
Factor out 2:
Find two terms that multiply to "c" (-16) and add up to "b" (6x)
Two terms that work are 8 and -2
Expand the expression:
Factor by grouping:
The factored expression is 2(x - 2)(x + 8).
Use the zero product property to solve for x:
x can be 2 or -8
