Find the GCF of the coefficients 84 and 210 by prime factorization, showing the factors used.
Factor completely: x3+x2−9x−9x^3 + x^2 - 9x - 9
Which factoring strategy is most efficient for x4−16x^4 - 16, and what is the complete factorization?
Which condition correctly describes the pair of numbers m and n used to factor x2+bx+cx^2 + bx + c as (x+m)(x+n)(x + m)(x + n)?
A box manufacturer models the number of items per layer as: N(x)=x2+9x+20N(x) = x^2 + 9x + 20. They want to solve for the linear expressions for the length and width in terms of xx. Factor N(x)N(x).
A manufacturer models volume per layer as: V(x)=x2−11x+30V(x) = x^2 - 11x + 30. If xx must be an integer and the company needs to solve for positive linear dimensions, which factorization will yield positive expressions for both linear factors?
Given a trinomial: 3x2+kx+43x^2 + kx + 4 which is factored as: (3x+m)(x+n)(3x + m)(x + n), which condition must mm and nn satisfy in order for the FOIL expansion to give back the original trinomial expression?
Use the AC method to factor 8x2−2x−158x^2 - 2x - 15.
Factor by trial-and-error: 12x2+7x−1012x^2 + 7x - 10
Factor the trinomial x2−7x+12x^2-7x+12 completely.
Two integers differ by 44 and their product is 4545. Using a variable and a quadratic equation, find those integers.
A rectangular playground has an area equal to three times the square of its width. If the length is 99 meters greater than the width, find the width and length.
