Look at all of this math. do it all or something for 50 points each ig
(a + b)2 = a2 + 2ab + b2
(a β b)2 = a2 β 2ab + b2
(a + b) (a β b) = a2 β b2
(x + a)(x + b) = x2 + (a + b)x + ab
(x + a)(x β b) = x2 + (a β b)x β ab
(x β a)(x + b) = x2 + (b β a)x β ab
(x β a)(x β b) = x2 β (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab(a + b)
(a β b)3 = a3 β b3 β 3ab(a β b)
(x + y + z) 2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
(x + y β z) 2 = x2 + y2 + z2 + 2xy β 2yz β 2xz
(x β y + z)2 = x2 + y2 + z2 β 2xy β 2yz + 2xz
(x β y β z)2 = x2 + y2 + z2 β 2xy + 2yz β 2xz
x3 + y3 + z3 β 3xyz = (x + y + z)(x2 + y2 + z2 β xy β yz -xz)
x2 + y2 = 1212 [(x + y)2 + (x β y)2]
(x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
x3 + y3 = (x + y) (x2 β xy + y2)
x3 β y3 = (x β y) (x2 + xy + y2)
x2 + y2 + z2 -xy β yz β zx = 1212 [(x-y)2 + (y-z)2 + (z-x)2]
