Question

Graph the function to find the area. Rewrite the function with the polynomial in factored form. y=x^2+2x-3 The zeros of the functions are ______.

Answer 1

Given the function:

`y=x^2+2x-3`

Factor:

`y=(x-1)(x+3)`

We find the zeros:

`(x-1)(x+3)=0`

So:

`\begin{gathered} x-1=0 \\ x-1+1=0+1 \\ x=1 \\ and \\ x+3=0 \\ x+3-3=0-3 \\ x=-3 \end{gathered}`

Answer:

the zeros are -3, 1

the polynomial in factored form y = (x - 1)(x + 3)
