Answer:
Step-by-step explanation:
If it is, the first and last terms are perfect squares, and the middle term is twice the product of the roots of those squares.
16x^ = (4x)^2 . . . . a perfect square
49 = 7^2 . . . . . . . a perfect square
-2(4x)(7) = -56x . . . . . matches the middle term, so the factoring is ...
16x^2 -56x +49 = (4x -7)^2
_____
The sign in the binomial factors is the same as the sign of the middle term of the trinomial.
C. 5 . The greatest common factor is the number that both numbers, 15 and 25, can have a number multiplied into.
For 15, it would be 5x3=15
For 25 it would be 5x5=25
1 isn’t the greatest, 3 isn’t the greatest, 15 cannot go into 25.
