Question

Factorize the expression: x 2 + 5x − 6

Answer 1

→ We can't solve  this question using Factorization method.

Answer:

x = 6    or    x = -1

Step-by-step explanation:

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

Using Quadratic formula,

x = [ -b ± √b² - 4ac ]/ 2a

x = [-5 ± √(5)² - 4(1)(-6)] / 2(1)

x = [-5 ± √25 + 24] / 2

x = [-5 ± √49] / 2

x = [5 ± 7] / 2

$x=\frac{5+7}{2} \\\\x=\frac{12}{2} \\\\x=6$

$x=\frac{5-7}{2} \\\\x=\frac{-2}{2} \\\\x=-1$

Answer 2

Answer:

${x}^{2} - 3x - 2x + 6 \\ x(x - 3) - 2(x - 3) \\ (x - 3)(x - 2) \\ x = 3 \: or \: x = 2$
