Answer:
a^2 -10a +16
Step-by-step explanation:
(a-2) • (a-8)
FOIL
first a*a = a^2
outer: a * -8 = -8a
inner: -2 *a = -2a
last: -2 *-8 = 16
Add them together
a^2 -8a -2a+16
Combine like terms
a^2 -10a +16
Answer:
The factored form of the equation is (x+4)(x-6)=0.
Step-by-step explanation:
Because (x-4)(x+2)=x^2-4x+2x-8=16,
so that means x^2-2x-8=16,
move 16 to the other side,
you get x^2-2x-8-16=0,
simplify,
you get x^2-2x-24=0,
which satisfies (x+4)(x-6)=0 when factored out.
Because (x+4)(x-6)=x^2+4x-6x-24=x^2-2x-24=0.
