Zina [86]

$y=-\frac{1}{2}(x+5)^2-2\\
y=-\frac{1}{2}(x^2+10x+25-2)\\
y=-\frac{1}{2}(x^2+10x+23)\\
$

this is not factorable so you must apply the quadratic formula and you'll end up with

x=-5-2i
x=-5+2i

What is g. 59 + 2p + 4 = 39 -8,

Lera25 [3.4K]

Hello there. Since g isn't on here, I'll solve for p.

First, solve anything that you can. 59+4 is 63. Subtract 63 from both sides.

2p=-32

p=-16

Therefore, the answer is p=-16.

Answer:

$\large\boxed{x=\pm\sqrt{13}}$

Step-by-step explanation:

$10x^2-6=144\qquad\text{add 6 to both sides}\\\\10x^2=130\qquad\text{divide both sides by 10}\\\\x^2=13\to x=\pm\sqrt{13}$
