User: factor each polynomial 12x^2-5x-3

Weegy: Factor each polynomial 12x^2-5x-3 = (4x - 3)(3x + 1), checking our factoring using FOIL F First terms 12x^2 O Outside terms +4x I Inside terms -9x L Last terms -3

User: use the difference of two squares formula to factor. Be sure to factor out any common factors. y^2-49

Weegy: y^2 - 49, next step is = y^2 - 7^2, and the last is = (y+7) (y-7). [smile]

User: use the difference of two squares formula to factor. Be sure to factor out any common factors. 4x^2-25

Weegy: Yeah, I will be sure, so The problem is (2x)^ 2 - 5^2 Then it will be (2x+5) (2x-5).

User: use the difference of two squares formula to factor. Be sure to factor out any common factors. 81x^2-1

Weegy: So this is the problem, 81x^2-1 , Then the factor is (9x - 1)(9x + 1).

User: Using the perfect square trinomial formulas to factor. Be sure to factor out any common factors. 16y^2-8y+1

Weegy: The answer is (4X-1)^2.

User: find all the roots and check your answers. x^2+5x-14=0

Weegy: Ok so this is the solution 1. x^2+5x-14=0 2.x^2+7x-2x-14=0 3.x(x+7)-2(x+7)=0 4.(x+7)(x-2)=0, Then the answer is x=-7 OR 2.

User: find all the roots and check your answers. 3x^2+5x=0

Weegy: Here is the solution: 3x^2+5x=0 next is x(3x+5)=0 then the answer is x=0 OR x= -5/3

User: find all the roots and check your answers. 49x^2-25=0

Weegy: This is the solution for 49x^2-25=0

49x^2-25=0
(7x + 5)(7x - 5) = 0
x = -5/7 or x = 5/7

Factor out the greatest common factor x^3+8x^2+2x+16
Weegy: Start with the given expression %28x%5E3%2B8x%5E2%29%2B%282x%2B16%29 Group like terms x%5E2%28x%2B8%29%2B2%28x%2B8%29 Factor out the GCF x%5E2 out of the first group. [ Factor out the GCF 2 out of the second group %28x%5E2%2B2%29%28x%2B8%29 Since we have the common term x%2B8, we can combine like terms So x%5E3%2B8x%5E2%2B2x%2B16 factors to %28x%5E2%2B2%29%28x%2B8%29 In other words, x%5E3%2B8x%5E2%2B2x%2B16=%28x%5E2%2B2%29%28x%2B8%29 ] (More)

for the polynomial function h(x)= 2x^4-x^3+2x^2-4x-3 evaluate the following h(3)
Question
Updated 6/9/2014 1:23:54 PM
h(x)= 2x^4 - x^3 + 2x^2 - 4x - 3, h(3):

h(x)= 2(3)^4 - (3)^3 + 2(3)^2 - 4(3) - 3;

h(x)= 2(81) - 27 + 2(9) - 12 - 3;

h(x)= 162 - 27 + 18 - 15;

h(x)= 135 + 3;

h(x)= 138
