%2812x%5E2%2B7%29%2F4x=10
12x%5E2%2B7=40x
12x%5E2-40x%2B7=0
Use the quadratic formula,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%2840+%2B-+sqrt%28+%28-40%29%5E2-4%2A12%2A7+%29%29%2F%282%2A12%29+
x+=+%2840+%2B-+sqrt%28+1600-336+%29%29%2F24+
x+=+%2840+%2B-+sqrt%28+1264%29%29%2F24+
x+=+%2840+%2B-+4sqrt%28+79%29%29%2F24+
highlight%28x+=+%2810+%2B-+sqrt%28+79%29%29%2F6%29
