Question

Write -72=2y^2-16y-20x in standard form

Answer 1

-72=-12y-20x

Explanation:

-72=2y^2-16y-20x

square the 2 keeping the variable

-72=4y-16y-20x

Then combine like terms in this case the numbers followed by y's

-72=-12y-20x

This is the standard form as there is nothing else you can combine to break this down any further

Answer 2

y = √ 10 ( x − 2 )

y = − √ 10 ( x − 2)+ 4 + 4
