2x%5E2-28x=50
2x%5E2-28x-50=0 <--- Subtract 50 from both sides
x%5E2-14x-25=0 <--- Divide both sides by 2
Use the quadratic formula,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%2814+%2B-+sqrt%28+14%5E2-4%2A1%2A%28-25%29+%29%29%2F2+
x+=+%2814+%2B-+sqrt%28+196%2B100%29%29%2F2+
x+=+%2814+%2B-+sqrt%28+296%29%29%2F2+
x+=+%2814+%2B-+2sqrt%28+74%29%29%2F2+
highlight%28x+=+7+%2B-+sqrt%28+74%29%29+
