I thinks it’s -x-4 I’m not sure
Answer:

Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 25 and 35 is 5
Divide both the numerator and denominator by the GCD
25 ÷ 5
35 ÷ 5
Use the substitution method

2(1)
= 2
2(2)
= 4
2(3)
= 6
F(x)=x^2+2x+1 & g(x)=3(x+1)^2
now, f(x)+g(x)
=x^2+2x+1+3(x+1)^2
=x^2+2x+1+3(x^2+2x+1)
=x^2+2x+1+3x^2+6x+3
=4x^2+8x+4<===answer(c)
next:
f(x)=x^2-1 & g(x)=x+3
now, f(g(x))=(x+3)^ -1
=x^2+6x+9-1
=x^2+6x+8<====answer(b)
i solve two of ur problems.
now try the 3rd one that is similar to no. 1
and try the last two urself.
