(i) x^2+ 11 x + 10
(ii) 2 X square + X - 15

Answer 1

hope this helps u please follow

Answer 2

${x}^{2} + 11x + 10 \\ {x}^{2} + x + 10x + 10 \\ x(x + 1) + 10(x + 1) \\ (x + 1)(x + 10)$
x = - 1 , x = -10
$2 {x}^{2} + x - 15 \\ 2{x}^{2} + 6x - 5x - 15 \\ 2x(x + 3) - 5(x + 3) \\ (x + 3)(2x - 5)$
x = - 3 , x = 5/2
