Factor using DOTS (do not take out the GCF first):
64x2 - 36
What is
(8x-6)(8x+6)
Is 37 a prime or composite number? Explain your reasoning.
37 is a prime number because the only factors of 37 are 1 and 37.
When the expression (2x+3)-5(x-2) is written is simplest form, what is the result?
-3x+13
Factor completely.
5x2 - 30x +45
What is
5(x−3)(x−3)
What is an equivalent expression to the following when factored completely?
-4x2+40x +96
What is
-4(x - 12)(x + 2)?
Is the following relationship a function? Why or why not?
{(-2, 4), (3, 6), (-2, 7), (2, 6), (9, -5)}
No. The x-value -2 is repeated, so the relationship cannot be a function.
Factor completely:
81x4 - 49x2
What is
x2(9x-7)(9x+7)
Factor: x4-5x3+3x2
x2(x2-5x+3)
Is the product of the square root of 5 and the square root of 16 rational or irrational? Explain your answer.
The product is irrational. When you multiply a rational and irrational number, the answer is always irrational.
OR
When you multiply them, the answer is a non-repeating, non-terminating decimal (8.94427...), so the product is irrational.
The result of factoring:
-3x2-9x-6
What is
-3x(x + 1)(x + 2)?
The result of factoring:
2x2 + 8x + 8
What is
2(x + 2)2?

Factor completely: -4y2+12y+72
-4(y+3)(y-6)
