Solve the following equation by using the quadratic formula.
9x^2 + 18x + 2 = 0
the quadratic formula:
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
In this problem a=9, b=18, c=2
x+=+%28-18+%2B-+sqrt%2818%5E2-4%2A9%2A2+%29%29%2F%282%2A9%29+
:
x+=+%28-18+%2B-+sqrt%28324+-+72+%29%29%2F%2818%29+
:
x+=+%28-18+%2B-+sqrt%28252%29%29%2F18+
Two solutions
x+=+%28-18+%2B+15.8745%29%2F%2818%29+
x = 2.12549%2F18
x = -.1181
and
x+=+%28-18+-+15.8745%29%2F%2818%29+
x = 33.8745%2F18
x = -1.882
