x2 - 9x + 8 = (x-1)(x-8)
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.
9x2 + 8x - 1 = (9x - 1)(x + 1)
(x+1)(x+8)
(3x - y+ 2)(3x + y + 2)
(9x)2 +9x/(45x)2 +81= 9+9x/86
9x2 + 8x - 1 = (9x - 1)(x + 1)
(x+1)(x+8)
3(x2 + 3x + 1)
(3x - y+ 2)(3x + y + 2)
You don't need to factor that; you can add them together, since they have the same variable.However, assuming you might mean 81x squared + 9x, you can take out the common factor, which is 9x.
(2x+3)(x+3)
(9x)2 +9x/(45x)2 +81= 9+9x/86
x2-9x+8=0 has two solutions:x = 8x = 1
3(2x - 3)(x + 3)
(x + 12)(x - 3)
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
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 .
