Find the polynomial function with the following roots: -2 of multiplicity 2; and 3.show work (dba questions of module 4)

f(x) = x³ + x² - 8x - 12

Step-by-step explanation:

given roots x = -2 of multiplicity 2 and x = 3, then

(x + 2)² and (x - 3) are factors and the polynomial is the product of the factors

f(x) = a(x + 2)²(x - 3) ← where a is a multiplier

f(x) = (x² + 4x + 4)(x - 3) ← with a = 1

     = x³ + x² - 8x - 12

30

step-by-step explanation:

times by times

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
