Chapter 5: Q.188 (page 536)

In the following exercises, multiply the binomials using a) the Distributive Property; b) the FOIL method; c) the Vertical Method
$(4 p + 11) (5 p - 4)$

Short Answer

Expert verified

The product of the given binomials is $20 p^{2} + 39 p - 44$

Step by step solution

Step 1. Given Information

The given binomials are $(4 p + 11) (5 p - 4)$

The product is to be determined using a) the Distributive Property; b) the FOIL method; c) the Vertical Method

Part (a) Step 1. Using distributive property

According to distributive property:

$(4 p + 11) (5 p - 4) = 4 p (5 p - 4) + 11 (5 p - 4) (4 p + 11) (5 p - 4) = 4 p (5 p) - 4 p (4) + 11 (5 p) - 11 (4) (4 p + 11) (5 p - 4) = 20 p^{2} - 16 p + 55 p - 44 (4 p + 11) (5 p - 4) = 20 p^{2} + 39 p - 44$

Part (a) Step 2. Conclusion

The product of the binomials is $20 p^{2} + 39 p - 44$

Part (b) Step 1. Using FOIL Method

Using FOIL method, the terms are multiplied in the order of First Terms, Outer Terms, Inner Terms and then Last Terms:

$(4 p + 11) (5 p - 4) = (4 p) (5 p) + (4 p) (- 4) + (11) (5 p) + (11) (- 4) (4 p + 11) (5 p - 4) = 20 p^{2} - 16 p + 55 p - 44 (4 p + 11) (5 p - 4) = 20 p^{2} + 39 p - 44$

Part (b) Step 2. Conclusion

The product of the binomials is $20 p^{2} + 39 p - 44$

Part (c) Step 1. Using Vertical Method

Multiplying the binomials using vertical method:

$\begin{matrix} 4 p & + 11 \\ 脳 & 5 p & - 4 \\ - 16 p & - 44 \\ 20 p^{2} & + 55 p \\ 20 p^{2} & + 39 p & - 44 \end{matrix}$

Part (c) Step 2. Conclusion

The product of the binomials is $20 p^{2} + 39 p - 44$
