Question

What are the zeros of the quadratic equation y=5(2x-1)(x+3)

Answer 1

The answer is x = 1/2 or -3

Answer 2

Answer:

x = 1/2 or -3

Step-by-step explanation:

to find the zeros, we need to find the values of x which would cause y to become zero,

i.e solve x for :  

5(2x-1)(x+3) = 0   (divide both sides by 5)

(2x-1)(x+3) = 0  

hence either

2x-1 = 0   (add 1 to both sides)

2x = 1    (divide both sides by 2)

x = 1/2   --> first zero

or

x+3 = 0   (subtract 3 from both sides)

x = -3 ----> 2nd zero
