If a = 9, b = 1, and c = –5, what does (a + b – c)(a – b + c) equal?

Back

45

Answer explanation

Directly substitute the given values into the corresponding variables and solve.

(a + b – c)(a – b + c) =

(9 + 1 – (–5))(9 – 1 + (–5)) = (15)(3) = 45

Back

25

Answer explanation

Directly substitute the given values into the corresponding variables and solve.

(m – n + p)(n – p) =

(10 – 2 + (–3))(2 – (–3)) = (5)(5) = 25

FLASHCARD QUESTION

Front

The expression (4x – 6y)(4y + 5x) is equivalent to:

Back

Answer explanation

Use the FOIL method:

First: 4x · 4y = 16xy

Outer: 4x · 5x = 20x2

Inner: –6y · 4y = –24y2

Last: –6y · 5x = –30xy

Combine like terms:

(4x-6y)(4y+5x)=16xy+20x2-24y2-30xy=20x2-14xy-24y2
