f(x)=x^2+2x+1, g(x)=3x+3

Answer 1

Answer 2

@Callisto

Answer 3

can you show me the steps please?

Answer 4

all you need to do is solve
x^2+2x+1 = 3x+3

put it in standard form:
x^2-x-2 = 0 subtracted 3x+3 from both sides and simplified.
(x+1)(x-2)=0 factored

you can take it from here. the answer is now obvious.

Answer 5

Equate them together and solve since f(x)=g(x)
x^2+2x+1=3x+3

Answer 6

so the values would be like 1 and -2?? im confused.

Answer 7

@.Sam.

Answer 8

no,
from here,
(x+1)(x-2)=0
you set each brackets =0,
(x+1)=0, (x-2)=0
then solve for 2 values of x

Answer 9

ohh so -1 and 2 thank you! :)

Answer 10

yes

Answer 11

thanks sam! :)
