Answer 1

QUESTION:

x² - 5x - 6.

Factorised it,

ANSWER:

Quadratic equation is in the form of

$a {x}^{2} + bx + c = 0$

we have to factorised it;

STEP 1 :

Split the middle term in such a way that it's sum equal to b i.e -5 and product equal to a × c that is -6

${x}^{2} - 5x - 6 \\ {x}^{2} - 6x + x - 6$

STEP 2 :

Taking common ;

$x(x - 6) + 1(x - 6)$

$(x + 1)(x - 6)$

are the factors.

so,

$x + 1 = 0 \\ x = - 1 \\ \\ x - 6 = 0 \\ x = 6$

FINAL ANSWER :

$\huge\red{x = - 1 \: or \: 6}$
