Answer 2

Answer:

( f + g )(x) is x³ + 3x² - 46

Step-by-step explanation:

Given: f(x) = x² - 36   and g(x) = x³ + 2x² - 10

we have to find ( f + g )(x)

( f + g )(x) = f(x) + g(x) = ( x² - 36 ) + ( x³ + 2x² - 10 )

                = x² - 36 + x³ + 2x² - 10

                = x³ + (1+2)x² - 36 - 10

                = x³ + 3x² - 46

Therefore, ( f + g )(x) is x³ + 3x² - 46
