Write a quadratic whose zeros are 1 and -4

( x - 1 ) ( x + 4 ) = 0.

Step-by-step explanation:

Let's see 1. To make this equal to zero you write x - 1 where you substitute 1 in x.

Again let's see -4. To make it equal to zero, you write x + 4 where you substitute -4 in x.

So, this results in ( x - 1 ) ( x + 4 ) = 0

a)(x-2)^2+(y-1)^2=9
