4a - 5a^2
If you mean: 5a2+24a-5 then it is (5a-1)(a+5) when factored
4a-2=7a-6 4=3a a=4/3
(7a - 1)(6a + 1)
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
-8/7a
solving by factoring 5a2
(5a2 - 3)(5a2 + 3)
Combine like terms, adding/subtracting the coefficients: (5a² + 6a + 2) + (7a² - 7a + 5) = (5+7)a² + (6-7)a + (2+5) = 12a² - a + 7 (5a² + 6a + 2) - (7a² - 7a + 5) = (5a² + 6a + 2) + (-7a² + 7a - 5) = (5-7)a² + (6+7)a + (2-5) = -2a² + 13a - 3
To factorize the expression 7a^2 - 8ab, you need to find the greatest common factor of the two terms. In this case, the common factor is a. So, you can factor out an 'a' to get a(7a - 8b) as the factored form of the expression. This means that 7a^2 - 8ab can be simplified as a multiplied by the quantity (7a - 8b).
5(a2-3)
8a(5a2-1)
5a^2 - 5a - 60 ---- 5(a2 + a - 12)
The GCF is 7a.
5a(a+2b+b²)
Since 7a is a factor of 14ab, it is automatically the GCF.
7a 7a * 4 = 28a 7a * 7b = 49ab
