Seven minus negative two times negative 4 is equal to -1
(5w + 1)(w + 1)
Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.
no
Negative 2 ☻ed is -4 and -4 - 5= -1. ♥

You have to put your heart into it!
Oh honey, that's just n times n minus n. So, n squared minus n is just n times (n-1). Hope that clears things up for ya, darling.
it equals positive one. one squared is always one. if they're both negative, negative times negative is always positive.

No, unless "a" happens to be equal to 0, or to 1.
Multiply both sides by sin(1-cos) and you lose the denominators and get (sin squared) minus 1+cos times 1-cos. Then multiply out (i.e. expand) 1+cos times 1-cos, which will of course give the difference of two squares: 1 - (cos squared). (because the cross terms cancel out.) (This is diff of 2 squares because 1 is the square of 1.) And so you get (sin squared) - (1 - (cos squared)) = (sin squared) + (cos squared) - 1. Then from basic trig we know that (sin squared) + (cos squared) = 1, so this is 0.
