3a + 27 = 0
1. First you subtract 27 from both sides to isolate 3a, the variable.
3a = -27
2. Divide both sides by 3 to get a by itself
a = -9
The final answer is a = -9

How do you factor sum or difference of two cubes?
Sum and difference of two cubes is factored this way : a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
What is the complete factor of a3 64?
(a + 4)(a^2 - 4a + 16)
What is the formula of a cube plus b cube?
This is the formula: (a3)+(b3)=(a+b)(a2-ab+b2)
How do you factor the expression x cubed minus 8?
(x3 - 8) is factored thus: (x - 2)(x2 + 2x + 4) The easiest way to do this is to remember the formula: (a3 - b3) = (a - b)(a2 + ab + b2)
How do you factor 125x3 plus 343y3?
125x3+343y3 can also be written (5x)3+(7y)3. It helps to rewrite the constants like this because there is a general factoring rule: a3+b3 = (a+b)(a2-ab+b2). In this example, the a is 5x and the b is 7y. Plug in and get (5x+7y)(25x2-35xy+49y2).
How do you factor a3-9a2 plus 3a?
a(a^2 - 9a + 3)
A3 plus b3 equals?
A3+b3
Factor a3 - 1?
(a - 1)(a^2 + a + 1)
How do you factor a times a cubed plus 2 times a times b plus b squared?
the answer to factorising (a x a3 + 2ab + b2) would be (a4+2ab+b2)
How do you factor sum or difference of two cubes?
Sum and difference of two cubes is factored this way : a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
Formula for a3 plus b3 plus c3?
kutta
What is the greatest common factor of letters with exponents?
Just choose the smaller exponent. The GCF of a3 and a5 is a3
What is the factor of a3 - 2a2 plus 4a - 8?
First you can factor a^2 from the first two terms and 4 from the last two terms. (a^2)(a-2)+4(a-2) You can see that they both have (a-2) as a factor. So it is (a^2+4)(a-2)
What is the formula of a3 plus b3?
(a+b)3=a3+b3+3ab(a+b) a3+b3=(a+b)3-3ab(a+b) a3+b3=(a+b)(a2-ab+b2)
How do you factor x cubed plus twenty seven?
The Answer:The sum of cubes, operation is: (a+b)(a2-ab+b2) = a3+b3So, since 27 = 33 we can reformulate to:So, x3+33 = (x + 3)(x2-3x+32) = (x + 3)(x2-3x+9).
What is the complete factor of a3 64?
(a + 4)(a^2 - 4a + 16)
What is the greatest common factor of 36 a3 b4?
The GCF is 1.
