Question

(x - 10)² - x (x + 17) = 104 simplificado

Answer 1

$\sf \left(x-10\right)^2-x\left(x+17\right)=104\\\\\\\sf \boldsymbol{\sf expandir~}\\\\\\\sf -37x+100=104\\\\\\\boldsymbol{\sf Subtrair\:100\:de\:ambos\:os\:lados}\\\\\\\sf -37x+100-100=104-100\\\\\\\boldsymbol{\sf Simplificar}\\\\\\\sf -37x=4\\\\\\\boldsymbol{\sf Dividir\:ambos\:os\:lados\:por\:-37}\\\\\\\sf \dfrac{-37x}{-37}=\dfrac{4}{-37}\\\\\\\boldsymbol{\sf Simplificar}\\\\\\\boxed{\sf x=-\frac{4}{37}}$
