Answer:

2x² +5x -12 = 0

Step-by-step explanation:

When p and q are roots of a quadratic, its factored form can be written as ...

(x -p)(x -q) = 0

Here, the roots are given as -4 and 3/2, so the factored form would be ...

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

Multiplying by 2 gives us ...

(x +4)(2x -3) = 0

Expanding the product, we find the desired quadratic is ...

2x² +5x -12 = 0
