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.
