Question

(x + 4)(x + 1) = (x + 2)²

Answer 1

Respuesta:

x=0

Explicación paso a paso:

(x + 4)(x + 1) = (x + 2)²

x²+5x+4=(x+2)²

x²+5x+4=x²+4x+4

5x+4=4x+4

x+4=4

x=0

Answer 2

Respuesta:

(x + 4)(x + 1) = (x + 2)²

(x)²+(4+1)x+(4(1)) = (x)²+2(2x)+4

x²+5x+4 = x²+4x+4

(1-1)x²+5x+4 = 4x+4

5x+4 = 4x+4

(5-4)x = 4-4

x = 0
