I'm giving another medal

OpenStudy (maemae16):

OpenStudy (kinged):

Figure out two numbers with product of 54 and sum of fifteen to begin with.

OpenStudy (maemae16):

its \[9*6 and 9+6\]

OpenStudy (maemae16):

is that right @Kinged

OpenStudy (maemae16):

@legomyego180

OpenStudy (kinged):

Yep. Now figure out the right signs.

OpenStudy (kinged):

Their product is positive but sum is negative. So what do you get from that?

OpenStudy (legomyego180):

should be in the form \[(x-?)(x-?)\] because you need two negatives multiplied together to make a positive, but still need to subtract -9 and -6 to get -15

OpenStudy (maemae16):

(x+9)(x+6)

OpenStudy (legomyego180):

9+6 is positive 15 you need -15

OpenStudy (maemae16):

(x-9)(x+6)

OpenStudy (kinged):

Try adding -9 and 6. What do you get?

OpenStudy (kinged):

Try multiplying the. What do you get? Are they the answers we want?

OpenStudy (maemae16):

not 15 so it would have to -9 and -6

OpenStudy (kinged):

Yep.

OpenStudy (maemae16):

so the answer is (x-9)(x-6)

OpenStudy (kinged):

Yes. That's how it's done.

OpenStudy (maemae16):

thank you

OpenStudy (maemae16):

and Thank You @legomyego180 i wish i could give you a medal too but it will only let me give 1
