Question

2 x cube minus 5 x square - 14 x + 8 break the solution​

Answer 1

Step-by-step explanation:

2x³ - 5x² - 14x + 8 = 0

put x = -2 we get 0 hence x = -2 is a root of the given equation

2x²(x+2) -9x(x+2) +4(x+2) = 0

(x + 2)(2x² -9x +4) = 0

(x + 2)(2x² -8x - x + 4) = 0

(x + 2){2x(x-4) -1(x-4)} = 0

(x+2)(x-4)(2x-1) = 0

x = -2, 4, 1/2
