4x^2 + 4x = 5 * (x+1) * x
Factor out x on the left side
(4x + 4) * x = 5 * (x+1) * x
Factor out 4 on the left side
4*(x + 1)* x = 5 * (x + 1) * x
But 4 can be written as (2 + 2)
So
(2 + 2) * (x + 1) * x = 5 * (x+1) * x
Divide both sides by (x + 1)*x
And you have
2 + 2 = 5
Factor out x on the left side
(4x + 4) * x = 5 * (x+1) * x
Factor out 4 on the left side
4*(x + 1)* x = 5 * (x + 1) * x
But 4 can be written as (2 + 2)
So
(2 + 2) * (x + 1) * x = 5 * (x+1) * x
Divide both sides by (x + 1)*x
And you have
2 + 2 = 5
2 + 2 = 5
