Factor difference of cubes formula
WebTo factor a difference of cubes, find a and b and plug them into (a - b)(a 2 + ab + b 2). Factoring a 3 + b 3. An expression of the form a 3 + b 3 is called a sum of cubes. The factored form of a 3 + b 3 is (a + b)(a 2 - ab + b 2): ... To factor a sum of cubes, find a and b and plug them into ... WebDo not write the factorization. To factor, first identify the quantities that are being cubed. The first term is the cube of xy, and the constant is the cube of 7. Next, use the formula to write the factors. The first factor is the sum of xy and 7. The second factor has three terms: the square of xy, the negative of 7xy, and the square of 7.

WebMar 26, 2016 · Example 1: Factor the difference between the cubes, 216 – 125. Use the difference of cubes rule to find the variables. In this case, The cube root of 216 is 6, and the cube root of 125 is 5; so 6 is the a, and 5 is the b. Substitute the values into the equation. 216 – 125 = (6 – 5) (36 + 30 + 25). Check to see if the equation is true. WebAs per the formula of difference of cubes, the first factor will be a binomial and the second factor will be a trinomial. a 3 – b 3 = (a – b) (a 2 + ab + b 2) The first factor has already been given here as the binomial (x-3) To get the second factor we will replace a = x and b = 3 in the trinomial expression (a 2 + ab + b 2)
