Answer:

  not necessarily

Step-by-step explanation:

Taking the square root of both sides, you have ...

  ±a = ±b

Those four cases resolve to two unique cases:

  a = ±b

The given equation will be true if a = b or if a = -b. If a and b are constrained to have the same sign, then a=b is the only solution.

4x^2 - 9y^6 <br> what patterns can be used ?<br> please and thank you !!!
S_A_V [24]

Answer:

<em>B. (U+V)(U-V)</em>

Step-by-step explanation:

<u>Factoring</u>

The given expression is:

4x^2-9y^6

It should be noted that both terms are perfect squares:

(2x)^2=4x^2

(3y^3)^2=9y^6

Since it's a difference of squares, we need to use the following pattern to factor the required expression:

(U^2-V^2)=(U+V)(U-V)

Thus, the answer is

B. (U+V)(U-V)
