Solve for x using the quadratic formula: x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a
7x%5E2+%2B+10x+=+-2 Add 2 to both sides.
7x%5E1+%2B+10x+%2B+2+=+0 Here, a = 7, b = 10, and c = 2
x+=+%28-10%2B-sqrt%2810%5E2-4%287%29%282%29%29%29%2F2%287%29 Simplify this.
x+=+%28-10%2B-sqrt%28156%29%29%2F14
x+=+%28-10%2F14%29%2B%282sqrt%2839%29%29%2F14 and x+=+%28-10%2F14%29-%282sqrt%2839%29%29%2F14 Simplifying a bit more.
x+=+%28-5%2F7%29%2B%28sqrt%2839%29%29%2F7 = %28-5%2Bsqrt%2839%29%29%2F7 and...
x+=+%28-5%2F7%29-%28sqrt%2839%29%29%2F7 = %28-5-sqrt%2839%29%29%2F7
