9x^2-(7x-2)(x+3)=-12x+1

Answers

Answer 1

Answer: 9x^(2)-(7x-2)(x+3)=12x+1
9x^(2)-(7x^(2))-2x+21x-6=-12x+1
2x^(2)+31x=7

Answer 2

Answer: 9x^2-(7x-2)(x+3)= -12x + 1
9x^2 - [7x^2 + 21x - 2x -6] = -12x+1
9x^2 - 7x^2 -19x +6 +12x - 1 = 0
2x^2 - 7x + 5 = 0
(x-1)(2x - 5)=0

there are two answers
1. x = 1
2. x = 5/2 or 2 1/2

you can try and substitute these numbers in to see if they are correct, because they are for me
