Answer:
(2x +5y)(2x − 5y) =
Step-by-step explanation:
(2x +5y)(2x − 5y) is the given equation.
Now, the <u>ALGEBRAIC IDENTITY</u> states that:
Here, comparing a = 2x and b = 5y,
we get (2x +5y)(2x − 5y) =
on further solving the right side, we get
(2x +5y)(2x − 5y) =
Put the values where the variables are, then do the arithmetic.
8 - 8/2 +7² = 8 - 4 + 49 = 53
Answer:
i think its C
Step-by-step explanation:
Notice that we have a difference of squares in the numerator of our expression. In the denominator we have a quadratic expression of the form
. So we can factor both numerator and denominator and cancel common terms:
We can conclude that the correct answer is the fourth one:
