Answer:

-p^2+32

Step-by-step explanation:

Start by expanding the -2 into the (p-4) bracket using the distributive method:

-2(p-4)\\-2p + 8

Now, expand the result into the remaining bracket:

(-2p + 8)(p+4)\\-2p^2 -8p+8p+32\\-2p^2 + 32

A father’s age is the square of his son’s age (x). In 20 years’ time the father will be 3 times as old as his son. What are the
VMariaS [17]

If the current son's age is x, the current age of the father is x^2.

In 20 years they will be, respectively, x+20 and x^2+20 years old, and we know that the father will be 3 times as old as his son:

x^2+20=3(x+20) \iff x^2+20=3x+60 \iff x^2-3x-40=0

The quadratic equation has solutions

x_{1,2}=\dfrac{3\pm\sqrt{9+160}}{2}=\dfrac{3\pm 13}{2}

So, the two solutions are

x_1 = \dfrac{16}{2}=8,\quad x_2 = \dfrac{-10}{2}=-5

We clearly can't accept negative values as solution for a problem involving the age of a person, so the only feasible solution is x=8, and we deduce that the father's age is 8 squared, i.e. 64.
