Question

4.ײ+ 9× + 18 = 0 solve this guys...​

Answer 1

Answer:

x²+(6+3)x+18=0

x²+6x+3x+18=0

x(x+6)+3(X+6)=0

(X+6)(x+3)=0

either,x+6=0.

x=-6

or,x+3=0

x=-3

Answer 2

OR

$\large{ {x}^{2} + 9x + 18} = 0 \\ \\ {x}^{2} + 6x + 3x + 18 = 0 \\ \\ x(x + 6) + 3(x + 6) = 0 \\ \\ (x + 6)(x + 3) = 0 \\ \\ x + 6 = 0 \: \: \: \: \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: \: \: \: x + 3 = 0 \\ \\ x = - 6 \: \: \: \: \: or \: \: \: \: \: \: x = - 3$
