First you input the equation into the quadratic formula:
__________
x=<span><span><span>−<span>(<span>−2</span>)</span></span>±<span>√<span><span><span>(<span>−2</span>)</span>2</span>−<span><span>4<span>(1)</span></span><span>(5)</span></span></span></span></span>
</span> -----------------------------
2(1)
Next you simplify the formula:
___
x=<span><span>2±<span>√<span>−16
</span></span></span></span> ------------

This problem has no real solutions.
Answer:
a) 510000000 c) 24.4 d) 502.3
Step-by-step explanation:
Answer:
the last one is the answer!
All real numbers. in interval notation, that's (<span><span>−∞</span>, ∞</span><span>). there isn't a value you could insert for "x" that would give you an error.</span>
