Question

Answer the following
7x+ X square -18 =0

Answer 1

Answer:

Step-by-step explanation:

x2+7x-18=0

factorize by spliting the midile term process

x2+9x-2x-18=0

take x common from first two terms

and -2 common in 2nd two terms

then

x(x+9)-2(x+9)=0

(x+9)(x-2)=0

x+9=0 and x-2=0

x= -9 and x= 2
