How do I Factor completely ?

Y² - 12y + 32

The middle term must be written in such a way that the sum of two numbers is -12y and the product is 32y²

The two such numbers are -4y and -8y

So, we can write:

y² - 4y - 8y + 32

= y(y - 4) - 8(y - 4)

= (y - 4)(y - 8)

So, option B gives the correct answer

Which expressions are equivalent to 12 - 14/3t + 2/3t? Select ALL that apply. Please show how you got the answer.
geniusboy [140]

Answer:

B and F

Step-by-step explanation:

Equivalent expressions are expressions which in simplest form are equal. Simplify each expression to see each equals the simplest form of 12 - 14/3 t + 2/3 t.

12 - 14/3t + 2/3 t simplifies to 12 - 12/3t = 12 - 4t.

The options are:

a. 8t

b. 12-4t

c. -4(3 + t)  = -12 - 4t

d. 4(t - 3)  = 4t - 12

e. 12 - 16/3t

f. -4(t - 3) = -4t + 12

b and f are equivalent
