Pulling out like terms

7.1 Pull out like factors :

8x7y2 + 18x5y3 + 6x2y4 = 2x2y2 • (4x5 + 9x3y + 3y2)

Trying to factor a multi variable polynomial :

7.2 Factoring 4x5 + 9x3y + 3y2

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Final result :
2x2y2 • (4x5 + 9x3y + 3y2)

What is the sum of the geometric series 2^0 + 2^1 + 2^2 + 2^3 + 2^3 + 2^4 + … + 2^9?
GREYUIT [131]
Sum is
S_{n}=\frac{a_{1}(1-r^{n})}{1-r}

r=common ratio
a1=first term
it looks like 2^0=1 is the first term aka a1
it goes to the 9th term (2^9)

sub
S_{9}=\frac{1(1-(2)^{9})}{1-2}
S_{9}=\frac{1-512}{-1}
S_{9}=\frac{-511}{-1}
S_{9}=511

Answer:

f(x) + g(x) = 3x + 7

Step-by-step explanation:

f(x) = 2x + 2, g(x) = x + 5

f(x) + g(x) = 2x + 2 +x + 5

f(x) + g(x) = 2x +x + 5 +2

f(x) + g(x) = 3x + 7
