x²+ 7x + 10 = 0

0-10 = 7x +x²

-10 = 7x + x²

-10/7 = x + x²

Answer 2

$\large \boxed{\tt \implies x = - 5}\: \\ \\ \large\boxed{\implies x = - 2}$

Step-by-step explanation:

$\bf {x}^{2} + 7x + 10 = 0 \\ \\ \bf \implies \: {x}^{2} + 5x + 2x + 10 = 0 \\ \\ \bf \implies x(x + 5) + 2(x + 5) = 0 \\ \\ \large\bf \implies(x + 2)(x + 5) = 0 \\ \\ \tt \: x + 5 =0 \: \: \: \: \: \: \: \: \: \: x + 2 = 0 \\ \\ \boxed{\tt \implies x = - 5}\: \: \: \: \: \boxed{\implies \: x = - 2}$
