2x2-2 = -5x-1 2x2+5x-2+1 = 0 2x2+5x-1 = 0 Use the quadratic equation formula to find the values of x: x = 0.1861406616 or x = -2.686140662
2x2 + 5x - 3 (2x - 1)(x + 3)
2x2+5x-3 = 0 (2x-1)(x+3) = 0 x = 1/2 or x -3
(x + 1)(2x - 7)
2x2+5x+3 = (2x+3)(x+1) when factored
2x2-2 = -5x-1 2x2+5x-2+1 = 0 2x2+5x-1 = 0 Use the quadratic equation formula to find the values of x: x = 0.1861406616 or x = -2.686140662
2x2 + 5x - 3 (2x - 1)(x + 3)
x3 + 2x2 + 5x + 4 = (x + 1)(x2 + x + 4)
2x2+5x+3 = (2x+3)(x+1) when factored
2x2 - 5x = 3 ∴ 2x2 - 5x - 3 = 0 ∴ 2x2 + x - 6x - 3 = 0 ∴ x(2x + 1) - 3(2x + 1) = 0 ∴ (x - 3)(2x + 1) = 0 ∴ x ∈ {-0.5, 3 }
2x2+5x-3 = 0 (2x-1)(x+3) = 0 x = 1/2 or x -3
(x + 1)(2x - 7)
2x2 - 5x + 6 = ?x = -1(2 x (-1)2) - (5 x -1) + 6 = ?(2 x 1) - (-5) + 6 = ?2 + 5 + 6 = 13
2x2+5x+3 = (2x+3)(x+1) when factored
First you should combine equal terms. For example, 2x2 and -4x2 can be combined as -2x2. Then you can use the quadratic formula.Additonal Answer:-2x2+5x+3-4x2+22 = 0Collect like terms: -2x2+5x+25 = 0Divide al terms by -1: 2x2-5x-25 = 0Factorise: (2x+5)(x-5) = 0Solutions are: x = -5/2 or x = 5
=2x2+x+4x+2=x(2x+1)+2(2x+1)=(2x+1)(x+2) by spaz licker enjoy slag ;)
If that's -5x, the answer is (x - 3)(2x + 1) x = 3, -1/2 If that's +5x, the answer is (x + 3)(2x - 1) x = -3, 1/2
