What are the solutions of 2x2 plus 18x-20 equals 0?
Using the quadratic equation formula: x = 1 or x = -10
How do you solve 11x equals 20x Plus 18?
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
What are the roots of the quadratic equation y equals 2x2 plus 3x-20?
2x2 + 3x - 20 = (x + 4)(2x - 5).
-4x2 plus 6x plus 40 equals 0?
-4x2 + 6x + 40 = 0 ∴ -2x2 + 3x + 20 = 0 ∴ -2x2 - 8x + 5x + 20 = 0 ∴ -2x(x + 4) + 5(x + 4) = 0 ∴ (5 - 2x)(x + 4) = 0 ∴ x ∈ {5/2, -4}
2x2 - 20x - 100 equals 6?
2x2 - 20x - 106 = 0 (20 +/- sqrt(400 + 848))/4 =(20 +/- sqrt 1248)/4 = (20 +/- 35.33)/4 = 55.33/4 or -15.33/4 = 13.83 or -3.83
