Question

$5 {x}^{2} + 26x + 5$

Answer 1

${5x}^{2} + 26x + 5 \\ {5x}^{2} + (25 + 1)x + 5 \\ {5x}^{2} + 25x + x + 5 \\ 5x(x + 5) + 1(x + 5) \\ (5x + 1)(x + 5)$

Answer 2

AHOY !!

_______________

${5x}^{2} + 26x + 5 \\ \\ {5x}^{2} + 25x + x + 5 \\ \\ Taking \: common \\ \\ 5x(x + 5) + 1(x + 5) \\ \\ 5x + 1 = 0 , x + 5 = 0 \\ \\ x = \frac{-1}{5} , x = - 5$
