Answer 1

Answer:

c

Step-by-step explanation:

x(x-4)(x-4)=0

(x-4)^2=0

(x-4)=0

x=4

Answer 2

Answer:

$\boxed{-4}$

Step-by-step explanation:

Distributive property:

     ↓

$A(B+C)=AB+AC$

$(x-4)(x-4)$

There are 2 terms from left to right equation.

$2x-4=-4$

Add by 4 both sides of equation.

$2x-4+4=-4+4$

Simplify.

$2x=-8$

Divide by 2 both sides of equation.

$\frac{2x}{2}=\frac{-8}{2}$

Simplify, to find the answer.

$-8\div2=-4$

-4 is the correct answer.
