x%5E2-5x=14
x%5E2-5x-14=0
Using the quadratic formula,
x=%285%2B-sqrt%285%5E2-4%2A1%2A%28-14%29%29%29%2F%282%2A1%29
x=%285%2B-sqrt%2825%2B56%29%29%2F%282%29
x=%285%2B-sqrt%2881%29%29%2F%282%29
x=%285%2B-+9%29%2F%282%29
x=%285%2B9%29%2F%282%29 or x=%285-9%29%2F%282%29
x=14%2F2 or x=-4%2F2
x=7 or x=-2
