Question

Evalute 6n2 − 14n − 36 given n(n − 6) = 16.

Smaller Value
Larger Value

Answer 1

Jimmy can you show me how you did the last one? Thanks!!

Answer 2

same as the last time... you do
n^2-6n-16=0

then factorise

(x-8)(x+2)=0
then x=8 or -2

Answer 3

Then you substitute those values into the first equation

Answer 4

HUH?

Answer 5

Oh sorry

Answer 6

um, when you substitute, the answers are

Answer 7

I can't get the larger number but the smaller number is 16 and I don't know how I got that even

Answer 8

-52 and and -32

Answer 9

Oh... well then... am not sure

Answer 10

-8 and 2 are definitely the substitution factors, however.

Answer 11

I mean, 8 and -2

Answer 12

order is right
6n2 − 14n − 36 given n(n − 6) = 16.

first thing find the values of n from the second equation
n(n-6)=16
n^2-6n-16=0
(n-8)(n+2)=0

n=8, -2

then u substitute n=8 in the first equation
6(8)^2-14(8)-36 and evaluate it

then substitute n=-2 in the same equation and evaluate it

Answer 13

SO, yes, the answers should be -52 and -32... double checked that answer

Answer 14

is it to the power of 2, or times it by 2?

Answer 15

power i guess

Answer 16

Hm. Ok, then that changes the final answers...

Answer 17

i think whoever askd the question should try to find them

Answer 18

Ok, well, that's the basics of it, good luck.. I hope you find the final answers! Do you have the answer booklet?
