Find the GCF of the coefficients 84 and 210 by prime factorization, showing the factors used.
In order to factor the polynomial: x3+6x2+9xx^3 + 6x^2 + 9x completely, should you factor out a GCF first? Why or why not?
Factor completely by grouping, after any necessary rearrangement: 2x3−x2−8x+42x^3 - x^2 - 8x + 4
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).
Which statement best explains why the method of finding two integers that multiply to cc and add to bb fails for: 2x2+5x+32x^2 + 5x + 3?
A design engineer examines the quadratic expression: P(x)=x2+(k)x+41P(x) = x^2 + (k)x + 41, where kk is an integer. They want to solve for the integer linear factors, but they must note that 4141 is prime. For which integer value(s) of kk can x2+kx+41x^2 + kx + 41 be factored into integers (x+m)(x+n)(x + m)(x + n)?
What is the product of the binomials (2x+3)(x+4)(2x + 3)(x + 4) when expanded by FOIL?

Use the AC method to factor 6x2+17x+5 6x^2 + 17x + 5.
Factor the perfect square trinomial x2+6x+9x^2 + 6x + 9 completely.
Factor the expression: 6x2+11x−356x^2 + 11x - 35 completely by using the grouping method or a trial-and-error approach when necessary.
