Question

(x-3) (2x+1) =(x-1) (x+3)​

Answer 1

Answer:

x²-7x

Step-by-step explanation:

(x-3) (2x+1) = (x-1) (x+3)

x(2x+1)-3(2x+1)= x(x+3)-1(x+3)

2x²+x-6x-3= x²+3x-x-3

2x²-5x-3= x²+2x-3

2x²-5x-3-x²-2x+3=0

2x²-x²-5x-2x-3+3=0

x²-7x

Answer 2

2x^2+x-3-6x=x^2+3x-x-3
x^2-7x=0
x(x-7)=0
x=0 , x=7
