You can put this solution on YOUR website!
You're missing an exponent.
Should it be 9x%5E2???
.
.
9x%5E2=48x-48
9x%5E2-48x-48=0
3x%5E2-16x-16=0
Use the quadratic formula,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%2816+%2B-+sqrt%28+16%5E2-4%2A3%2A%28-16%29+%29%29%2F%282%2A3%29+
x+=+%2816+%2B-+sqrt%28+256%2B192+%29%29%2F%286%29+
x+=+%2816+%2B-+sqrt%28+448%29%29%2F%286%29+
x+=+%2816+%2B-+8sqrt%28+7%29%29%2F%286%29+
highlight%28x+=+%288+%2B-+4sqrt%28+7%29%29%2F%283%29%29+
