Question

(x+b) 2-(x-a2)-(a+b)2=0​

Answer 1

Respuesta:

$x=-a^2+2a$

Explicación paso a paso:

$\left(x+b\right)\:2-\left(x-a2\right)-\left(a+b\right)2=0\\\\\left(x+b\right)\cdot \:2-\left(x-a^2\right)-\left(a+b\right)\cdot \:2+\left(a+b\right)\cdot \:2=0+\left(a+b\right)\cdot \:2\\\\\left(x+b\right)\cdot \:2-\left(x-a^2\right)=2\left(b+a\right)\\\\x+2b+a^2=2b+2a\\\\x+2b+a^2-\left(2b+a^2\right)=2b+2a-\left(2b+a^2\right)\\\\x=-a^2+2a$
