Question

Write the equation 16x2 + 25y2 − 32x + 50y + 16 = 0 in vertex form.

Answer 1

We have the following equation given:

`16x^2+25y^2-32x+50y+16=0`

We can complte the squares and we have this:

`16(x^2-2x)+25(y^2+2y)+16=0`
`16(x^2-2x+1)+25(y^2+2y+1)+16=16+25`

And then if we simplify we got:

`16(x-1)^2+25(y+1)^2=25`
`((x+1)^2)/(((5)/(4))^2)+((y+1)^2)/(1)=1`
