Answer:
Step-by-step explanation:
Although you can start with 4x^2-2x-4=0, it's just slightly easier to reduce the coefficients. 4x^2-2x-4=0 becomes 2x^2 - x - 2 = 0.
The discriminant (part of the quadratic formula) is b^2 - 4ac. Using b = -1. a = 1 and c = -2, we get (-1)^2 - 4(2)(-2), or 17.
-b ± √(b^2 - 4ac)
Then the quadratic formula x = ---------------------------
2a
-(-1) ± √17 1 ± √17
takes on the values x = ----------------- = ---------------

Answer:
5x^2 + 3x +4
Step-by-step explanation:
(2x^2 + x + 3) + (3x^2 + 2x + 1)
Combine like terms
(2x^2 + 3x^2 + 2x+ x + 3 + 1)
5x^2 + 3x +4
