Question

Help solve

`{x}^(2) - 4x = 0`

Answer 1

remember, if ab=0, assume that a=0 and b=0

`x^2-4x=0`

factor

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

solve x=0 and x-4=0

x=0

x-4=0

x=4

so x=0 and 4

Answer 2

ANSWER: 0,4

x(x−4)=0 Step 1: Factor left side of equation.

x=0 or x−4=0 Step 2: Set factors equal to 0.

x=0 or x=4
