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)
What is 2a plus 3b equals 6ab?
With the assumption your asking what a or b are in terms of each other. a=3b/(6b-2) b=2a/(6a-2)
When can you multiply the denominators to find the LCD?
Ex: 3/a + 4/b = 7, LCD is ab ab x (3/a) + ab x (4/b) = ab x 7 3b + 4a = 7ab so that the denominators have cancelled. a and b can represent binomials, monomials, polynomials, etc. EX: 3/(x+2) + 4/(x-5) = 7 multiply by ab = (x+2)(x-5)
What does 3gb and 375mb have in common?
3b
What is the greatest common factor of 672 and 1470?
4704= 2 x 2352= 2 x 2 x 1176= 2 x 2 x 2 x 588= 2 x 2 x 2 x 2 x 294= 2 x 2 x 2 x 2 x 2 x 147= 2 x 2 x 2 x 2 x 2 x 3 x 49= 2 x 2 x 2 x 2 x 2 x 3 x 7 x 7672= 2 x 336= 2 x 2 x 168= 2 x 2 x 2 x 84= 2 x 2 x 2 x 2 x 42= 2 x 2 x 2 x 2 x 2 x 21= 2 x 2 x 2 x 2 x 2 x 3 x 7The prime factors they have in common are 2 x 2 x 2 x 2 x 2 x 3 x 7, so the greatest common factor is 672.
What is the answer to 2a x 3b?
2a x 3b = 6ab
What is 3b x b?
The expression 3b x b can be simplified by multiplying the coefficients (numbers) and the variables separately. In this case, 3b x b simplifies to 3b^2, where b^2 represents b squared. This means you multiply the coefficient 3 by the coefficient 1 (since b can be thought of as b^1) to get 3, and you multiply the variable b by itself to get b^2.
6b squared minus 3b divided by 3b?
6b^2 - 3b / 3b 6b^2 - 1 or ( 6b^2 - 3b) / 3b = 2b - 1 Or (6b^2 - 3b ) / 3b = 3b(2b - ) / 3b = 2b - 1
6xminus 3b plus 8 equals 16?
6x - 3b + 8 = 16.Since you cannot simplify the equation, the answer is 6x - 3b = 8.However, if you would like to find x, you can substitute b with '0':6x - 3b + 8 = 166x - 3b = 86x - 3(0) = 86x = 86 6x = 1.33 or 1(1/3)If you want to find b, you can substitute x with '0':6x - 3b + 8 = 166x - 3b = 86(0) - 3b = 8-3b = 8-3 -3b = -2.66 or -2(2/3)
-2b plus 7-3b equals 2?
-2b + 7 -3b = 2 -2b +7 -3b +2b = 2 + 2b 7 -3b + 3b = 2 + 2b +3b 7-2 = 2-2 + 2b + 3b 5 = 5b 1 = b
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)
Factorise 4a plus 6b-12?
2 x (2a + 3b - 6)
What is the LCM of 24a 3b and 36ab 2?
24a 3b and 36ab 2
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
Simplify 3q x -3b x -6a?

What is the answer to 3b plus 6 equals 12?
3b + 6 = 12 3b = 6 b = 2
3b - 2 equals 7b plus 4?
3b -2 =7 b+4
