Question

(x+4).(x+4) = (x+1).(x+10)

Answer 1

(x+4)(x+4)=x²+8x+16
(x+1)(x+10)=x²+11x+10

x²+8x+16=x²+11x+10
x²-x²+8x-11x+16-10=0
-3x+6=0
-3x=-6
3x=6
x=2

O valor de X é 2

Answer 2

(x+4).(x+4)=(x+1).(x+10)
x^2+4x+4x+16=x^2+10x+x+10
x^2-x^2+4x+4x-10x-x+16-10
4x+4x-10x-x+16-10
8x-11x+6=0
-3x+6=0
-3x=0-6
-3x=-6.(-1)
3x=6
x=6/3
x=2
