how do I factor this? f(z)=24y2-145

OpenStudy (mathstudent55):

It's not factorable.

OpenStudy (tjhawkes):

what about into 29 and 5?

OpenStudy (mathstudent55):

Yes, 145 is 5 * 29, but 24 = 2^3 * 3 and 24 and 145 have no factors in common.

OpenStudy (tjhawkes):

ok thank you

OpenStudy (bobo-i-bo):

I guess you can use messy square roots and fractions

OpenStudy (mathstudent55):

Also, why is this a function of z, but there is only y in the expression?
