Given:2x%5E2%2B5x-12=0
wheresystem%28a=2%2Cb=5%2Cc=-12%29
Solving the discriminant:b%5E2-4ac=5%5E2-4%2A2%2A-12=25%2B96=121
Continuing by Quadratic:
x=%28-5%2B-sqrt%28121%29%29%2F%282%2A2%29=%28-5%2B-11%29%2F4
x=%28-5%2B11%29%2F4=6%2F4=highlight%283%2F2%29
x=%28-5-11%29%2F4=-16%2F4=highlight%28-4%29
We'll see the graph;

Thank you,
