2x2 + 11x + 15 = (x + 3)(2x + 5).
13x + 15 = 11x - 5 2x = -20 x = -10
11x + 5y
2x2 + 11x + 12 = 2x2 + 3x + 8x + 12 = x*(2x + 3) + 4*(2x + 3) = (2x + 3)*(x + 4)
14 + 2x + 9x - 6 - 11x 14 - 6 + 2x + 9x - 11x The x values cancel themselves out, leaving just the number value The answer is therefore 8.
2x + 6 + 9x = 39 11x + 6 = 39 11x = 39 - 6 11x = 33 x = 3
2x2 + 11x + 15 = (x + 3)(2x + 5).
180=11x+9x. 180 = 20x. 18=2x. 9=x.
2x = 11x + 4 Subtract 11x from both sides: -9x = 4 Divide both sides by -9: x = 4/(-9) = -0.444...
13x + 15 = 11x - 5 2x = -20 x = -10
(11 plus or minus the square root of 129) divided by 4x = 5.589454172900137x = -0.0894541729001368
6x^2 + 11x + 4 is a Quadratic Statement. It is NOT an equation, because there is no 'equals' (=). It will factor to ( 3x + 4)(2x + 1)
11x + 5y
2x2 + 11x + 12 = 2x2 + 3x + 8x + 12 = x*(2x + 3) + 4*(2x + 3) = (2x + 3)*(x + 4)
2x + 9x simplified would be 11x
14 + 2x + 9x - 6 - 11x 14 - 6 + 2x + 9x - 11x The x values cancel themselves out, leaving just the number value The answer is therefore 8.
