x×x+x×4−6x−6×4
Factor out x from the expression
x(x+4)−6x−6×4
Factor out −6 from the expression
x(x+4)−6(x+4)
Factor out x+4 from the expression
(x−6)(x+4)
(x−6)(x+4)=0
When the product of factors equals 0,at least one factor is 0
x−6=0x+4=0
Solve the equation for x
More Steps
Evaluate
x−6=0
Move the constant to the right-hand side and change its sign
x=0+6
Removing 0 doesn't change the value,so remove it from the expression
x=6
x=6x+4=0
Solve the equation for x

Evaluate
x+4=0
Move the constant to the right-hand side and change its sign
x=0−4
Removing 0 doesn't change the value,so remove it from the expression
x=−4
x=6x=−4
