Question

solve: x^2 + 7x= -12 PLEASE HELP

Answer 1

x^2 + 7x= -12

x^2 + 7x + 12 = 0

Find two numbers that multiply to 12 AND add to 7. They are: 4 and 3

So x^2 + 7x + 12 factors to (x+4)(x+3)

which means

x^2 + 7x + 12 = 0

turns into

(x+4)(x+3) = 0

Answer 2

wait you arent'suppose to supbtract 7x from that side and send it to the other side?

Answer 3

OH WAIT NEVERMIND

Answer 4

no, you want everything on one side

Answer 5

mhmm and that's the final answer right?

Answer 6

no

Answer 7

if (x+4)(x+3) = 0, then either x+4=0 or x+3=0

so x = ?? or x = ??

Answer 8

the answer is 4 and 3 right?

Answer 9

close, but not quite

Answer 10

NOPE NEGATIVE

Answer 11

yep -4 or -3

Answer 12

OKAY THANKS :) while you're at it wanna answer another one :)

Answer 13

sure

Answer 14

okayx^2 + 4x +4 = 36

Answer 15

x^2 + 4x +4 = 36

x^2 + 4x +4 - 36 = 36 - 36

x^2 + 4x - 32 = 0

Find two numbers that multiply to -32 AND add to 4

Answer 16

OKAY OKAY i get it thank you SOO much for the help! I really appreciate it.

Answer 17

4 and pl

Answer 18

hmm okay lemme try and figure this out. STAY ON THOUGH.

Answer 28

No x= -8 & x= +4

Answer 29

Either: "complete the square" or use the "quadratic equation".

Answer 30

Whichever you do... that is the answer. No lol.

Answer 31

so it's x^2 +4x+4=36
x^2 +4x +4 -36+36-36
x^2 +4x-32=)
(x+8)(x-4)
x= -8,4
corret?
