Part a: factor 2x2y2 + 6xy2 + 18x2y2. show your work. part b: factor x2 + 10x + 25. show your work. part c: factor x2 − 36. show your work.

A.

B.

C.

Step-by-step explanation:

Part A. The expression consists of three terms: The first and the last terms are like terms, we can add them:

Now,

So,

Part B. The expression is a square of so

Part C. Use the difference of squares formula:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
