Answer:

Explanation:

Don't make life difficult with decimals. First multiply both sides with 10 to get rid of decimals.

10 (3x^2 + 2.5x) = 10 (12.5)

30x^2+ 25x = 125 (now rearrange to write in quadratic form)

30x^2 + 25 x - 125 = 0 (now we know a = 30, b= 25, c = -125)

Final answer x = 5/3 , -5/2
