Question

[8.07] Factor Completely: 25x2 − 36

(25x − 6)(x + 6)

(25x + 6)(x − 6)

(5x + 6)(5x − 6)

(5x − 6)(5x − 6)

Answer 1

This is the factorization of a difference of two squares, which factorizes into the product of a sum and a difference.

Follow this pattern.
\(a^2 - b^2 = (a + b)(a - b) \)

Answer 2

Is it C (5x + 6)(5x − 6)

Answer 3

its multiple choice, the right answer is right there...just distribute to check each one

yes it C

Answer 4

[8.02] Determine the factors of 15x2 + 3xy + 10x + 2y.

(3x + 2)(5x + y)

(5x + y)(2x + 3)

(3x + y)(5x + 2)

(5x + 3)(2x + y)

Answer 5

In this case, you have a 4-term polynomial.
To factor it, use factoring by parts.
First, factor a common term out of the first two terms and factor a common term out of the last two terms.
What do you get?
