Presumably this is a quadratic equation question in the form of:

a2+0.7a-0.1 = 0

Using the quadratic equation formula will give you:

(a+0.8216990566)(a-0.1216990556) = 0

Therefore: a = -0.8216990566 or a = 0.1216990566

Check that your answer is correct by multiplying out the brackets you should end up with: a2+0.7a-0.1 = 0
