Question

Revolva a equação do 2 grau

a) x² - 7x = 0

Answer 1

$\large\sf{} {x}^{2} - 7x = 0 \\ \large\sf{}x \times\left(x - 7\right) = 0 \\ \large\sf{}x = 0 \\ \large\sf{}x - 7 = 0 \ \\ \\ \large\sf{}x = 0 \\ \large\sf{}x = 7 \\ \\ \\ \large\sf{} x_{1} = 0 \\ \large\sf{} x_{2} = 7 \\ \\ \bm{\large\boxed{\boxed{  { \large \sf x_{1} = 0}}}}\bm{\large\boxed{\boxed{  { \large \sf x_{2} = 7}}}}$
