Answer:
-14
Step-by-step explanation:
8x-y²-3
8(-1/4) - (3)² - 3
-2 - (9) - 3
= -14
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.
Did you try the square root of 4? 2?
If you mean when 2 numbers are left. then you would, add the numbers together and then divide them by 2
