You can put this solution on YOUR website!
a=1, b=-5, c=-24 Plug them into the Quadratic Formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%285+%2B-+sqrt%28+%28-5%29%5E2-4%2A1%2A-24+%29%29%2F%282%2A1%29+
x+=+%285+%2B-+sqrt%28+25%2B96+%29%29%2F%282%29+
x+=+%285+%2B-+sqrt%28+121+%29%29%2F%282%29+
x+=+%285+%2B-+11%29%2F%282%29+
x+=+%285+%2B+11%29%2F%282%29=+16%2F2=8
or
x+=+%285+-+11%29%2F%282%29=-6%2F2=-3+
