the area of a rectangle is 2x^2+15x+18. find the expression for the length and the width FACTOR!!

(x+6)(2x+3) and it doesn't matter which one is the length and the width

what are the factors for the trinomial x^2+8x-9

(x+9)(x-1)

3x^2-x-10

(x-2)(3x+5)

x^2-5x+4

(x-4)(x-1)

what are the factors for the polynomial 12a^3b^2-18a^2b^4+6ab

-6ab(-2a^2b+3ab^3-1)

what are the factors for the polynomial x^2+5x?

x(x+5)

8r^3-64r^2+r-8

(r-8)(8r^2+1)

x^2-x-20

(x+5)(x-4)

6xy-8x+15y-20

(3y-4)(2x+5)

what is the degree of -5a^2b^3c^7

12 degree

write a trinomial with a degree of 8 and a constant term of 3

12a^2b+13c^2b^6+3

24x^3y^4z^2

2^3 times 3 times x times x times x times y times y times y times y times z times z

GCF of monomials, 14a^3b^2, 18ab^4, easy

2ab^2

14a^3b^2+18ab^4

2ab^2(7a^2+9b^2)

the area of a rectangle can be written as the polynomial 6x^2+7x-20. if the length of the rectangle is 2x+5, what is the other dimension?

3x-4

perfect squares, these are stupid but there is an easier way to do it with perfect squares

ex: 4x^2-9= (2x+3)(2x-3) ex: x^2-100= (x+10)(x-10)
