n² - 10n + 24 = 0 You need two numbers that multiply to equal 24. They have to add to equal -10. -6 times -4 is 24 -6 plus -4 is -10 Your answer is (n - 6)(n - 4).
40n2 + 40n = 40n(n + 1) ------------------ That is as factored as far I can see it being factored.
(y + 7)(y + 7)
x2 - 14x + 49(x - 7) (x - 7)
49 + 49 + 49 + 49 + 49 = 245 OR 49*5=245
(x + 7)(x2 - 7x + 49)
Doesn't factor evenly, use quadratic equation
(4x + 7)(16x2 - 28x + 49)
Factoring requires you to reduce as much as possible. To factor 7x + 49, you remove the common factor of 7x and 49, which is 7, and multiply (7x + 49)/7 (which is x + 7) by 7, without actually simplifying. 7x + 49 = 7(x + 7) Then, if possible, do the same thing until it cannot be further factored.
