If f(x)=4x^2-5x+7 and g(x)=3x^2-2x+8, find f(x) + g(x)

7x² - 7x + 15

Step-by-step explanation:

When we add two polynomial we add the co-efficient of the like terms. i.e., the coefficients of x², x and the constant term.

Given: f(x) = 4x² - 5x + 7

and     g(x) = 3x² - 2x + 8

f(x) + g(x) = 4x² - 5x + 7 + 3x² - 2x + 8

⇒ f(x) + g(x) = 7x² - 7x + 15

Hence, the answer.

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
