2x2 + 7x + 6 = 2x2 + 4x + 3x + 6 = 2x(x + 2) + 3(x + 2) = (x + 2)(2x + 3)
x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
(x + 3)(x - 1)
2x + 3 = x + 1 Subtract x from both sides: x + 3 = 1 Subtract 3 from both sides: x = -2
no posible answerImproved Answer:-2x2+x-3 = (2x+3(x-1) when factored
2x = x+3 2x-x = 3 x = 3
(2x + 3)(x + 1 ) = 2x^2 +5x +3
x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5
2x + 3 = x 2x + 3 - 3 = x - 3 2x = x - 3 2x - x = x - 3 - x x = -3
x - 2x + 3 = 3 - x
x + 3 + 2x = x + 3 subtract x + 3 to both sides 2x = 0 divide by 2 to both sides x = 0
6x with 3 over the x, because that is how many x's there are.
2x=x+3=x=3
2x = 4x + 3 -2x = 3 x = -3 / 2
2x-3 = x+5 2x-x = 8 x = 8
2x-3=x+2 2x-x=2+3 x=5
2x+2=x+5 x=3
