Solve for X cant answer it please help

Question

5x^2=8x+4

please I cant figure it outt i have been trying for hours and i still cant figure it out

Answer 1

Get the equation in standard form for a quadratic equation, and then use the quadratic formula.

5x² = 8x + 4

Standard form:

5x² - 8x - 4 = 0

a = 5

b = -8

c = -4

x = [-b ± √(b² - 4ac)] / (2a)

Plug in the numbers and get 2 solutions:

x = 2, x = -0.4
