It is: (x-2)(x-7) when factored
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
That factors to 3x(3x - 1)
(9x2 + 7)(9x2 - 7) = 81x4 - 49
(3x + 8)(3x - 8)
This is a difference of two squares, which factorises to: (3x - 4y)(3x + 4y)
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
With the help of the quadratic equation formula
x = -2/3,7/6
(9x + 7)(x - 2)
2x2-9x+4 = (2x-1)(x-4) when factored
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.
x2-9x+8=0 has two solutions:x = 8x = 1
(x + 12)(x - 3)
9x2-9x-10 = (3x+2)(3x-5) when factored
Dividend: x3+4x2-9x-36 Divisor: x+3 Quotient: x2+x-12
(9x)2 +9x/(45x)2 +81= 9+9x/86
(x + 2)(3x - 1)(3x + 1)
