Question

Use the quadratic formula to solve x2 + 8x + 9 = 0. Estimate irrational solutions to the nearest tenth.

{–6.6, –1.4}
{–18, 10}
{–13.3, –2.7}
{–3.7, 14.3}

Answer 1

Dianna67 is right. The answer is (-6.6, -1.4). If you use the quadratic formula, you will get two solutions:

-4 - sqrt of 7 & sqrt of 7 - 4

Answer 2

I'm Pretty Sure It Would Be Answer A. {-6.6, -1.4}
