Question 8 of 10 In the polynomial below, what number should replace the question mark to produce a difference of squares? X2 + ? x-25 А. 0 B. 25 C. 10 D. 5 SUBNET​

A) The number should be 0

Step-by-step explanation:

The differences of squares formula is x²-a²=(x+a)(x-a)

If we expand (x+a)(x-a), we see that it's x²-ax+ax-a² where -ax+ax=0 since the coefficients cancel out. Therefore, option A is correct.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
