Step 1: Simplifying the given equation :
Simplify the given equation
Given equation,
5x−2−3x+6=4x
⇒5(x+6)−3(x−2)(x−2)(x+6)=4x
⇒5x+30−3x+6x2+6x−2x+12=4x
⇒2x+36x2+4x−12=4x
⇒x2+18x=2x2+8x−24
⇒x2−10x−24=0
Step 2: Factorizing the above equation:
Factorize the above equaion
⇒x2−12x+2x−24=0‘{factorizing left hand side}
⇒x(x−12)+2(x−12)=0
⇒(x−12)(x+2)=0
⇒x−12=0 or x+2=0 {zero product rule}
∴x=12 or x=−2
Hence, the required answer is x=12 or x=−2.
