SUPER URGENT! 1) g(x) = 2x
f(x)=-2x + 2x
Find g(x) + f(x)

2) g(x)= 4x + 5
F(x)=-3x² – 3x
Find g(x) + f(x)

1) 2x+(-2x+2x)=2x
2) 4x+5+(-3x^2-3x)=-3x^2+x+5

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
