The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.
-4 + 10 + 6a - 2a + 3 9 + 4a
6a - 4 = -2(+ 4 on both sides)6a = 2(divide both sides by 6)a = 2/6a = 1/3
3a^2 + 3a^2 = 6a^2 3a^2 - 3a^2 = 0 3a^2 x 3a^2 = 9a^4 3a^2 divided by 3a^2 = 1
-4 plus 4 equals zero.
34
a= -4
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
(4, 3)
In order to solve something, there needs to be an equation. If I have read your equation right you have: (a² - 4)/(2 + 6a) x (3 + 9a)/(a² + 5a + 6) This looks like it needs to be simplified. There are two fractions being multiplied, so multiply the numerators and denominators together, giving: (a² - 4)/(2 + 6a) x (3 + 9a)/(a² + 5a + 6) = ((a² - 4)(3 + 9a)) / ((2 + 6a)(a² + 5a + 6)) Now, simplify the polynomials to remove the squared terms and any common factors: a² - 4 = (a - 2)(a + 2) 2 + 6a = 2(1 + 3a) 3 + 9a = 3(1 + 3a) a² + 5a + 6 = (a + 3)(a + 2) Giving: ((a² - 4)(3 + 9a)) / ((2 + 6a)(a² + 5a + 6)) = ((a + 2)(a - 2)3((1 + 3a))/(2(1 + 3a)(a + 3)(a + 2)) This can now be simplified by cancelling out equivalent terms, giving: ((a + 2)(a - 2)3(1 + 3a))/(2(1 + 3a)(a + 3)(a + 2)) = ((a - 2)3) / (2(a+3)) = 3(a - 2) / 2(a + 3) = (3a - 6) / (2a + 6)
so 5a = -20 making a = -4
The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.
(9a + 2)(9a + 2)
A = 4 (7x4) + 8 = 36 (6x4) + 14 = 36
a2+9a+20 = (a+4)(a+5) when factored
-4 + 10 + 6a - 2a + 3 9 + 4a
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
