In Exercises 106–108, factor and simplify each algebraic expression.
106. 16x
+ 32r4
107. (x² – 4)(x² + 3) - (r? – 4)°(x² + 3)2
108. 12x+ 6x
Make Sense? In Exercises 135–138, determine whether each
statement makes sense or does not make sense, and explain your
reasoning.
135. Knowing the difference between factors and terms is
important: In (3x?y)“, I can distribute the exponent 2 on
each factor, but in (3x² + y)', I cannot do the same thing
on each term.
136. I used the FOIL method to find the product of x + 5 and
x + 2x + 1.
137. Instead of using the formula for the square of a binomial
sum, I prefer to write the binomial sum twice and then
apply the FOIL method.
138. Special-product formulas have patterns that make
their multiplications quicker than using the FOIL
method.
In Exercises 83–90, perform the indicated operation or operations.
83. (3x + 4y)? - (3x – 4y)
84. (5x + 2y) - (5x – 2y)
85. (5x – 7)(3x – 2) – (4x – 5)(6x – 1)
86. (3x + 5)(2x - 9) - (7x – 2)(x – 1)
87. (2x + 5)(2r - 5)(4x? + 25)

In Exercises 135–138, determine whether each statement makes sense or does not make sense, and explain your reasoning. 135. I use the same ideas to multiply (V2 + 5) (V2 + 4) that I did to find the binomial product (x + 5)(x + 4). 136. I used a special-product formula and simplified as follows: (V2 + V5)? = 2 + 5 = 7. 137. In some cases when I multiply a square root expression and its conjugate, the simplified product contains a radical. 138. I use the fact that 1 is the multiplicative identity to both rationalize denominators and rewrite rational expressions with a common denominator.arrow_forwardIn Exercises 132–137, factor each polynomial.
