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)
