Unfortunately, you can't. If it were x2 + 2x - 3 ... you could factor it into (x-1)(x+3). Hope I helped!

Added:
X =[ - 2 (+/-) sqrt(- 8)]/2
would be the answer in complex fashion and and i, imaginary number answer would be forthcoming.
Two is a prime factor of that equation.

no
9x^(2) + 16 DOES NOT factor. Remember ; two squared terms with a plus(+) between them DOES NOT factor However, two squared terms with a minus(-) between them DOES factor . Hence 9x^(2) + 16 = (3x)^2) + 4^(2) does NOT factor However, 9x^(2) - 16 = (3x)^2) - 4^(2) does factor to ( (3x - 4)(3x + 4) Note the two different signs.

Factor out -2: -2(x squared +11x-20). This is fully factored.
it is 2y squared + 3y
(x-1)(x+2)
x2 + 36 cannot be factored. You can only factor the difference of two squares, not the sum.
Five squared is 25, and two squared is 4. When you add these together, 25 plus 4 equals 29. Therefore, five squared plus two squared is 29.
By factoring I get x-3 divided by x+3
(a - 2)(a^2 + 6)
