Chapter 7: Q. 316 (page 893)

In the following exercises, solve.
$(y - 11) (y + 1) = 0$

Short Answer

Expert verified

The solution is $y = 11, - 1 .$

Step by step solution

Step 1. Given Information.

The given equation is $(y - 11) (y + 1) = 0$

Step 2. Solution of the equation.

Using the Zero Product property,

$(y - 11) (y + 1) = 0 y - 11 = 0 T h e r e f o r e, y = 11 A l s o, y + 1 = 0 y = - 1$

Step 3. Check the solution,

On substituting $y = 11,$

$(11 - 11) (y + 1) = 0 (0) (y + 1) = 0 0 = 0$

which is true.

Now, substitute $y = - 1,$

$(y - 11) (- 1 + 1) = 0 (y - 11) (0) = 0 0 = 0$

which is true.
