Can anyone help me solve this equation. I have tried it but the answer I get is totally different to what's in the mark scheme 3x squared -2x plus 2-x squared equals 2?

sorry it wouldn't let me put brackets in. it should read
3x^2 -2x + (2-x)^2 = 2
3x2-2x+4-4x+x2=2
4x2-6x+4=2
4x2-6x+2=0
2(2x2-3x+1)=0
2(x-1)(2x-1)=0
x=1 or x=1/2

Who is the maker of linear equations?
Anyone can, if they know how to do it. A linear equation describes a straight line. Its equation contains an equals sign; + and - signs; positive and negative numbers; and a term having x in it, but not x squared or cubed or to any higher power. So one could look like this: 5x - 3 = 7x - 12, and by using the rule "add the same to both sides or subtract the same from each side the equation can be rewritten as : (5x -5x) + -3 +12 = 7x - 5x + (-12 +12 ), turning the ones in the brackets to zero, giving 9 = 2x So 2x = 9 which means that x = 9/2 = 4.5
