For which actual values of x is it fulfilled that 2x (x - 5) = -(3x + 1) ?

2x(x - 5) = -(3x + 1)

Distributive property.

2x^2 - 10x = -3x - 1

Move all terms to one side.

Add 3x to both sides, and add 1 to both sides.

2x^2 - 7x + 1 = 0

AC method is not possible, so we will use the quadratic formula.

7 +/- √49 - 8 / 4

7 +/- √41 / 4

7 +/- 6.40 / 4

(7 + 6.40)/4 = 3.35

(7 - 6.40)/4 = 0.15
