Question

Find the roots of x2+4x-252=0

Answer 1

Answer:

x=-18,x=14

Step-by-step explanation:

x²+4x-252=0

x²+18x-14x-252=0

(x²+18)(-14x-252)=0

x(x+18)-14(x+18)=0

(x+18)(x-14)=0

***x+18=0

x=0-18

x=-18

***x-14=0

x=0+14

x=14

Answer 2

Answer:

$given \: {x}^{2} + 4x - 252 = 0 \\ \: \: \: \: \: = {x}^{2} + 18x - 14x - 252 \\ \: \: \: \: \: = x(x + 18) - 14(x + 18) \\ \: \: \: \: \: = (x + 18) \: \: (x - 14) \\ \: \: \: \: \: therefore \: \: x = - 18 \: (or) \: 14$
