Question

The solutions of the quadratic equation 8+2x - 15x^2 = 0

Answer 1

Solution :

8 + 2x - 15x² = 0

15x² - 2x - 8 = 0

15x² - 12x + 10x - 8 = 0

3x(5x - 4) + 2(5x - 4) = 0

(3x + 2)(5x - 4) = 0

→ 3x + 2 = 0

x = -2/3

→ 5x - 4 = 0

x = 4/5

Answer 2

Step-by-step explanation:

8 +2x -15x²=0

or, 15x²-2x-8=0

or, 15x² -12x +10x -8=0

or, 3x(5x-4) + 2(5x-4)=0

or, (5x-4) (3x+2) =0

or, x = 4/5 , -2/3
