Question

write equation in standard form:

1.) y=x^2+5x+6

2.) y=-3x^2-1

3.) x^2+y^2=16

4.) (x-2)^2+(y-1)^2=9

5.) y^2+(x+1)^2=25

7.) x^2+6x+y^2=27

8.) x^2+y^2-4y=12

9.) x^2+4y^2=36

10.) 36x^2+9y^2=324

11.) x^2+2x+y^2-6y=15

Answer 1

how should we begin?

Answer 2

We should help him not solve all of them

Answer 3

i agree

Answer 4

how about we each tackle one, and then he can take it from there

Answer 5

yeap, from the first one

Answer 6

y=x^2+2*x*5/2+(5/2)^2-(5/2)^2+6

Answer 7

can u see how and can u work out from here

Answer 8

the third one is already in standard form for a circle
