(x2y2)3 + (x3y3)2 = 2x6y6.
You are given: G(x) = x2 + x So if you want to solve G(2), all you need to do is replace all occurrences of "x" with the number 2, then work out what it comes to. G(2) = 22 + 2 ∴G(2) = 4 + 2 ∴G(2) = 6
(16 x 22)2 = (16 x 4)2 = (64)2 = 4096. Always perform the operations inside parenthesis first.
(4x ^2 + 3) + (3x ^2 + 8) = ( 4x^2 + 3x^2 ) + (3+8) = 7x^2 + 11
(y2 - 2) (2y + 5)This is a fine opportunity to apply the FOILmethod of algebra.'FOIL' is a memory word to help you remember how to multiply two binomials ... exactly the task presented here.'FOIL' stands for 'First', 'Outside', 'Inside', 'Last'. Those are the four pairs of terms you have to multiply, and then add the four products together.First: (y2...) (2y...) = 2y3Outside: (y2...) (... +5) = 5y2Inside: (... -2) (2y... ) = -4yLast: (... -2) (... +5) = -10Add all 4 results, and there you have it: 2y3 + 5y2- 4y - 10
