How fo you factor 14a2-21a?
Usually, the easiest way to do this is to find a pair of numbers whose sum is equal to the coefficient of the first term, and whose product is equal to the product of the coefficients of the first and last terms: a + b = -3 a * b = -10 take all possible pairs of numbers that multiply to make negative ten: 1 * -10 = -10 -1 * 10 = -10 2 * -5 = -10 -2 * 5 = -10 and then find which one of those pairs also adds up to negative three: 1 + (-10) = -9 -1 + 10 = 9 2 + (-5) = -3 -2 + 5 = 3 So 2 and -5 are the coefficients we want. Now take our original equation: 10a2 - 3a - 1 and separate the middle term into two terms using those coefficients: 10a2 - 5a + 2a - 1 You can then factor a common term out of the first pair and last pair of terms: 5a(2a - 1) + 1(2a - 1) and then group your coefficients: (5a + 1)(2a - 1) Giving you the answer.
What does factor by grouping mean?
ex: 2x2 + 6bx + 5x + 15b Group 1st 2 terms and last 2 terms. Factor separately. = (2x2 + 6bx) + (5x + 15b) Factor using gcf = 2x(x + 3b) + 5(x + 3b) notice the parenthesis are the same = (2x + 5)(x + 3b)
6ab plus 9b divided by 2a plus 3?
(6ab + 9b)/(2a + 3) = 3b(2a + 3)/(2a + 3) = 3b
What is 2a x 3b?
2a x 3b = 6ab
What is the answer to 2a x 3b?
2a x 3b = 6ab
What is 2a divided by 6ab?
0.3333
3a plus 3b-2a plus 5b?
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
2A plus 3B times 2A - 3B?
2A plus 3B times 2A - 3B = 4A2 - 9B2; this is an example of the general formula (a + b)(a - b) = a2 - b2.
What is the answer to 2a squared plus 7ab plus 3b squared?
(2a + b)(a + 3b)
What is 16a plus 3b-c-5a plus 3b plus 7c plus a equals?
12a + 6b + 6c = 6(2a + b + c)
What is 6ab-3b factorize?
6ab-3b factorize = 3
What is the simplification of 6ab over 3b?
6ab / 3b = 2a so b / b cancels each other out 6 / 3 = 2 / 1 Example: a = 4 and b = 5 6ab = 6 x 4 x 5 = 120 3b = 3 x 5 = 15 120 / 15 = 24 / 3 = 8 = 2a = 2 x 4
What is 1a plus 2a plus 3b plus 4b and what is the answer?
1a+3b 2a+4b=3a +7b
Simplify 4a plus 7b plus 6a-3b-2a?
11a+7b-(3b-2a)
