Skysthelimit Group Title Solve. x^2 + 8x = 24 –4 ± 2 √ 2 –4 ± 2√ 10 –4 ± 2√ 5 –4 ± 2√ 7 one year ago one year ago

1. Skysthelimit Group Title

would it be the 2nd one?

2. AnimalAin Group Title

Move the constant term to the LHS and use the quadratic formula, or complete the square.

3. Skysthelimit Group Title

I know how to do it just looking for someone to check my answer and make sure its correct

4. AnimalAin Group Title

$x^2 + 8x = 24 \implies x^2 + 8x +16=24+16 \implies (x+4)^2=40$ $\implies x+4= \pm \sqrt{40} \implies x=4 \pm \sqrt{40}$

5. AnimalAin Group Title

$4 \pm \sqrt{40} =4 \pm 2 \sqrt {10}$
