I'm a little confused with finding the standard form. Would someone please help me? Write the following equation in standard form. Then solve

OpenStudy (study.geek.123):

Yes?

OpenStudy (scarlettfarra2000):

\[5q ^{2}-4q=4q^2-8q+45\]

OpenStudy (anonymous):

you want to put everything on one side of the equal sign

OpenStudy (scarlettfarra2000):

The standard form of a quadratic equation is \[ax^2+bx+c=0\]

OpenStudy (anonymous):

easiest would be to subtract \(4q^2\) add \(8q\) and subtract \(45\) from both sides

OpenStudy (scarlettfarra2000):

\[5q^2-q^2-8q+45\] Where would we add 8q?

OpenStudy (anonymous):

it is not \[5q^2-q^2\] it is \[5q^2-4q^2\]

OpenStudy (scarlettfarra2000):

So it would stay the same even after we cross it out?

OpenStudy (anonymous):

i am not sure what you mean what is 5 apples minus 4 apples?

OpenStudy (scarlettfarra2000):

1

OpenStudy (anonymous):

1 what?
