HEL g(a)=4a+3, h(a)=a^2+2a Find (g-h)(a)

(g-h)(a)   =   -a² + 2a + 3

Step-by-step explanation:

To find (g-h)(a) , we will follow the steps below:

From the question given

g(a)=4a+3

h(a)=a²+2a

so

(g-h)(a)   = g(a) - h(a)

            = 4a + 3  - (a² + 2a)

                = 4a + 3 - a² - 2a

                 = 2a + 3 - a²

                = -a² + 2a + 3

(g-h)(a)   =   -a² + 2a + 3

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
