3x^2+3x-60=3(x^2+x+20)=3(x+5)(x-4)
20x2 - 3x + 10 does not have any real factors.
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.
(x - 6)(x + 9)
(x - 2)(2x + 7)
2(5x - 1)(3x - 2)
3x squared minus 25x minus 28
(x + 2)(3x - 1)(3x + 1)
20x2 - 3x + 10 does not have any real factors.
3x^2 -14x +15 = (3x-5)(x-3)
(x - 6)(x + 9)
(x - 2)(2x + 7)
2(5x - 1)(3x - 2)
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
x(3x - 2)
(x-3)(3x+1)
The factors are [3x + 5 - 2*sqrt(10)] and [3x 5 + 2*sqrt(10)].
x³ + x² - 3x - 3 = (x + 1)(x + √3) (x - √3).
