$(a) (b - 3) (b + 6) b 脳 b + 6 b - 3 b - 18 b^{2} + 3 b - 18 (b) (4 y + 5) (4 y - 10) 4 y 脳 4 y - 10 脳 4 y + 20 y - 50 16 y^{2} - 40 y + 20 y - 50 16 y^{2} - 20 y - 50$

Step by step solution

Step 1

$G i v e n i n f o r m a t i o n (a) (b - 3) (b + 6) (b) (4 y + 5) (4 y - 10)$

Step 2

The mnemonicFOILFOILtells us exactly what terms to multiply, and in what order:

First 鈥� multiply thefirst terms
Outside 鈥� multiply theoutside/outer terms
Inside 鈥� multiply theinside/inner terms

Step 3

$P a r t (a) . S t e p 1 M u l t i p l e b y F O I L m e t h o d (a) 1 . M u l t i p l y f i r s t t e r m b^{2} 2 . M u l t i p l y o u t e r t e r m b^{2} + 6 b 3 . M u l t i p l y i n n e r t e r m b^{2} + 6 b - 3 b 4 . M u l t i l p y l a s t t e r m b^{2} + 6 b - 3 b - 18 5 . C o m b i n e l i k e t e r m s b^{2} + 3 b - 18$

Step 4

$P a r t (b) . S t e p 1 M u l t i p l y b y F O I L m e t h o d (b) 1 . M u l t i p l y f i r s t t e r m 16 y^{2} 2 . M u l i t p l y o u t e r t e r m 16 y^{2} - 40 y 3 . M u l i t p l y i n n e r t e r m 16 y^{2} - 40 y + 20 y 4 . M u l t i p l y l a s t t e r m 16 y^{2} - 40 y + 20 y - 50 5 . C o m b i n e l i k e t e r m 16 y^{2} - 20 y - 50$
