Question

(x-1) (x+6) -(x-2) (x-3) =3​

Answer 1

x(x+6)-1(x+6)-1(x-2)(x-3)=3

x^2+6x-1(x+6)-1(x-2)(x-3)=3

x^2+6x-x-6-1(x-2)(x-3)=3

x^2+5x-6-1(x-2)(x-3)=3

x^2+5x-6-x(x-3)+2(x-3)=3

x^2+5x-6-1x^2+3x+2(x-3)=3

x^2+5x-6-1x^2+3x+2x-6=3

x^2+5x-6-1x^2+5x-6=3

x^2+5x-12-1x^2+5x=3

5x-12+5x=3

10x-12=3

10x-12+12=3+12

10x=15

10x/10=15/10

x=3/2
