Question

Which of the following products is equal to x^2-5x-6? (a)(x+1)(x-6)(b)(x-2)(x-3)(c)(x+2)(x-3)(d)(x-1)(x-5)

Answer 1

Given equation,

$x^{2} -5x-6=0$

Solving, we get,

$x^{2} -5x-6=0\\\implies x^{2} -6x+x-6=0\\\implies x(x-6)+1(x-6)=0\\\implies (x+1)(x-6) = 0$

Option A) is your answer.

                                                   

Answer 2

${x}^{2} - 5x - 6 \\ \\ = > {x}^{2} - 6x + x - 6 \\ \\ = > x(x - 6) + 1(x - 6) \\ \\ = > (x + 1)(x - 6)$

Option A is correct...
