HELP! I Algebra 2 Quadratics?

Question

Which equation has the solutions x =1/2 and x =3/4 ?
1. 8x2 + 10x + 3 = 0
2. 8x2 – 10x – 3 = 0
3. 8x2 + 10x – 3 = 0
4. 8x2 – 10x + 3 = 0

Answer 1

To get the correct solutions:

(x - 1/2)(x - 3/4) = 0

Multiply the first set of parentheses by 2 and the second by 4.

(2x - 1)(4x - 3) = 0
8x² - 10x + 3 = 0

The answer is 4.
