okay so i’m pretty sure you asking to solve for x: 5x^2 -4x = 6. so first you want to move all parts of the problem to one side of the equation, so you’ll subtract both sides by 6. this gives you 5x^2 - 4x - 6 = 0. because this equation is quadratic, you know need to factor it out. (5x + 3)(x - 2). by using the quadratic formula, you find the (most precise) answer to be x = 2/5 +/- (the square root of 136)/10. this can be simplified further but it is not longer precise. hope this helps!
