How do you factor y2 - xy - 56x2?
Some signs would have helped answerers but for what its worth 7 & 8 are factors of 56 which differ by 1 so how about: (y - 7x)(y + 8x) which are the factors of y2 + xy - 56x2 or (y + 7x)(y - 8x) which are the factors of y2 - xy - 56x2.

Factor 5x squared 8x minus 21?
To factor the expression (5x^2 + 8x - 21), we look for two numbers that multiply to (5 \times -21 = -105) and add to (8). These numbers are (15) and (-7). We can then rewrite the expression as (5x^2 + 15x - 7x - 21) and factor by grouping: (5x(x + 3) - 7(x + 3)). Thus, the factored form is ((5x - 7)(x + 3)).
What is the complement of Y if Y equals 8X-20 degrees?
Complementary angles add up to 90 degrees so if y = 8x-20 degrees then the complement of y is 90 - (8x - 20) = 110 - 8x degrees.
