Chapter 8.5, Problem 43E

To determine

To determine the error and correct it.

Answer to Problem 43E

Zeros are -3 and 2. There is an error in the signs.

Explanation of Solution

Given information :

Given equation is,

  $y=5\left(x+3\right)\left(x-2\right)$

Now we shall find the zeros of the given function we get,

  $0=5\left(x+3\right)\left(x-2\right)$

Now we know that $\left(x+3\right)=0,\left(x-2\right)=0$

Now solving this we get,

  $x=-3,x=2$

Zeros are -3 and 2. There is an error in the signs.
