What does 9a squared equal?
9a squared = 81a^2
What is 3a squared?
9a- a number is squared when it is multiplied by itself, so 3a x 3a = 9a.
How do you solve -21 equals 9a-15-3a?
-21 = 9a - 15 - 3a -6 = 6a -1 = a
How do you solve 9a plus 4a equals 26?
9a + 4a = 26 13a = 26 a = 26/13 a = 2
How do you solve this equation 4a-2.1 equals 9a plus 5.4?
4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5
How do you factorise 9a²-25?
34
How do you solve 1.5a plus 6 equals 9a plus 12?
a= -0.8
4a squared minus 9a plus 5?
4a2 - 9a + 5 = 4a2 - 4a -5a + 5 = 4a(a - 1) - 5(a - 1) = (4a - 5)(a - 1)
How do you Factor the trinomial 2a squared - 9a-18?
(a - 6)(2a + 3)
Solve the equation 9a-a equals 19 plus 7a?
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
How do you solve a squared minus 4 over 2 plus 6a times 3 plus 9a over a squared plus 5a plus 6?
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)
What is 3a sqared plus 9?
3a squared plus nine = 19a. 3a to the second power = 9a plus 9 = 19a.
