Standard form for both equation with steps

16x^2-96x+144+25y^2=400

16x^2+192x+576+25y^2=1600

These are the same kind. I'll do one.

Do them by completing the square:

16x^2-96x+144+25y^2=400
16(x^2-6x+9) + 25y^2 = 400
16(x-3)^2 + 25y^2 = 400

Now divide by 400 and you have

(x-3)^2/25 + y^2/16 = 1

To write both equations in standard form, you need to rearrange the terms so that the variables are listed in alphabetical order and the constant term is on the other side of the equation. Here are the steps for both equations:

Equation 1: 16x^2 - 96x + 144 + 25y^2 = 400

Step 1: Combine the constant terms on one side of the equation:
16x^2 - 96x + 25y^2 = 400 - 144

Step 2: Simplify the equation:
16x^2 - 96x + 25y^2 = 256

Equation 2: 16x^2 + 192x + 576 + 25y^2 = 1600

Step 1: Combine the constant terms on one side of the equation:
16x^2 + 192x + 25y^2 = 1600 - 576

Step 2: Simplify the equation:
16x^2 + 192x + 25y^2 = 1024

Now, both equations are in standard form. Equation 1 is: 16x^2 - 96x + 25y^2 = 256, and Equation 2 is: 16x^2 + 192x + 25y^2 = 1024.
