4x^2 - 13x + 3 = 0;
(x - 3) (4x - 1) = 0;
(x - 3) = 0 or (4x - 1) = 0;
x = 3 or 4x = 1; x = 1/4

The roots of 4x^2 - 13x + 3 = 0 are x = 3 or x = 1/4

(16x^2-56x+40)÷8 = 2x^2-7x+5
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)

divide (x^3+2x^2-3x+2)÷(x+1)
Weegy: (x^3+2x^2-3x+2)÷(x+1) = x^2+x-4 with a remainder of 6. (More)
Question
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
