Question

f(x)= 3x^2 +5x-z
g(x)=5x^2 -3x+z
m(x)=2x^2-2x

Answer 1

Write an expression to represent 2( f(x) -g(x) ) + 3(m(x))

Answer 2

Answer 3

first tell me what f(x)-g(x) is equal to

Answer 4

-2x^2 +7x?

Answer 5

@jim_thompson5910

Answer 6

close but no

Answer 7

5 minus -3 is not 7

Answer 8

isn't it 5 +3 cuz the -3 became a positive once i distributed the negative signs to all numbers?

Answer 9

yes 5 minus -3 = 5+3 = 8

Answer 10

ohh oh I'm sorry i dont know what i was thinking

Answer 11

f(x)-g(x) = -2x^2 + 8x

Answer 12

yea

Answer 13

what is 2*(f(x) - g(x)) equal to?

Answer 14

-4x^2 +16x?

Answer 15

yes

Answer 16

m(x)=2x^2-2x

what is 3*m(x) equal to?

Answer 17

6x^2 -6x

Answer 18

2( f(x) -g(x) ) + 3(m(x))
turns into
-4x^2+16x + 6x^2-6x
simplify that further

Answer 19

2x^2 +10?

Answer 20

close, it's actually 2x^2+10x

Answer 21

oh yea i forgot the x

Answer 22

thank you!

Answer 23

sure thing
