1. 3x2+12= 3(x2+4) 2. 7x2+35x= 7x(x+5)
7(5x + 9y)
7(5x + 4y)
35x + 15x = 50x
Well, let's start by breaking down the numbers and variables. The LCM, or least common multiple, is the smallest multiple that both numbers share. For 35x^8 and 245x^7, we can see that the common factors are 5, 7, and x^7. So, the LCM would be 5 * 7 * x^7, which simplifies to 35x^7.
The GCF is 5x3
1. 3x2+12= 3(x2+4) 2. 7x2+35x= 7x(x+5)
25x + 35x + 9 is 60x + 9, which factors to 3(20x + 3)
7(5x + 9y)
I'm guessing that's 35x^2 + 26x - 16 which factors to (5x - 2)(7x + 8)
7(5x + 4y)
5 * 7 * x * x * x
gcf(35x², 7xy², 21x²y²) = 7x 35x² = 5 times 7 times x² 7xy² = 7 times x times y² 21x²y² = 3 times 7 times x² times y² hcf = 7 times x = 7x (I've written the multiplication as times instead of using the × symbol to avoid confusion with the unknown x.)
(5x - 7)(7x + 5)
Factor: x3 - 12x2 + 35x 1. Factor out a x: x(x2 - 12x + 35). 2. Factor x2 - 12x + 35 which is (x-5)(x-7). 3. Answer: x(x-5)(x-7).
35x
7(5x + 9y)
