I'M DESPERATE FOR HELP!

[PuppyGirl]

I've been out of school sick for five days. I'm just about caught up with my homework. I just have tihs and another subject to do.

Directions: Find all real-number solutions. I've been factoring the equations to solve them, but on these I'm really stuck.

x^2+8x+16=0
Hint: an awnser is -4

2x^2-x=3
2x^2-x-3=0
Hint: a couple of the awnsers are 3/2, -1

How do I find the awnsers?(show work) :?

"x^2+8x+16=0
Hint: an awnser is -4"

Factored: (x + 4)(x + 4) = 0

"2x^2-x=3
2x^2-x-3=0
Hint: a couple of the awnsers are 3/2, -1"

Factored: (2x - 3)(x + 1) = 0
