2021-07-16· Check the mathematical signs; the \(\ b^{2}\) term is positive, not negative, when factoring a sum of cubes. The correct answer is \(\ (5 x+4)\left(25 x^{2}-20 x+16\right)\). Difference of Cubes. Having seen how binomials in the form \(\ a^{3}+b^{3}\) can be factored, it should not come as a surprise that binomials in the form \(\ a^{3}-b^{3}\) can be factored in a similar way. The Difference ...

Cubic Feet Calculator (feet, inches, cm, yards)

Divide the total by 1728 (as there are 1728 cubic inches in a cubic foot). As an example, let's say you're looking for the capacity of a box that measures 55" x 30" x 15". Multiplying those 3 figures together gives you a total cubic inches value of 24750in 3. To convert that figure to cubic feet we divide it by 1728, giving a total of 3.

Factoring Cubic Polynomials - UC Santa Barbara

Factoring Cubic Polynomials March 3, 2016 A cubic polynomial is of the form p(x) = a 3x3 + a 2x2 + a 1x+ a 0: The Fundamental Theorem of Algebra guarantees that if a 0;a 1;a 2;a 3 are all real numbers, then we can factor my polynomial into the form p(x) = a 3(x b 1)(x2 + b 2c+ b 3): In other words, I can always factor my cubic polynomial into the product of a rst degree polynomial and a second ...

Factoring: Some Special Cases

There are similar formulas to factor some special cubic polynomials: As an example, let us factor the polynomial We can rewrite this polynomial as Now it matches formula (5) with a=2x and b=3. Consequently The polynomial has a triple root at x=3/2. Sums and differences of two cubes. here are two more formulas to handle special cases of cubic polynomials: Say, we like to factor . By formula (6 ...

The "Cubic Formula"

This trick, which transforms the general cubic equation into a new cubic equation with missing x 2-term is due to Nicolò Fontana Tartaglia (1500-1557). We apply the substitution to the cubic equation, to obtain: Multiplying out and simplifying, we obtain the "depressed" cubic Let's try this for the example 2x 3-30x 2 +162x-350=0. Our substitution will be x=y+5; expanding and simplifying, we ...

Cubic equations -

This means that x+1 is a factor and the cubic can be written in the form (x+1)(x2 +ax+b) = 0 We can perform synthetic division to find the other factors. As before, we take the coefficients of the original cubic equation, which are 1, 0, −7 and −6. These are written down in the first row of a table, the starting layout for which is 1 0 −7 −6 x = −1 1 To the right of the vertical ...
