4x2 + 34x + 42
First, we can see that each term is divisible by two, so we'll factor that out:
= 2(2x2 + 18x + 21)
To further factor the remaining trinomial, we need to find two numbers whose product is equal to the product of our first and last terms' coefficent, and whose sum is equal to the end term's coefficient. In other words, we need two numbers that add up to 18, and multiply to make 42....
Factors of 42 are 2, 3 and 7. That means that our possible combinations of numbers are: 2 and 21, 6 and 7, or 3 and 14. Unfortunately, none of these can be added up to make 18, so the polynomial can not be factored any further.

Factor x2 plus x - 42?
44
How do you factor -x2 plus x plus 42?
-x2 + x + 42 = -[x2 - x - 42] = -[x2 - 7x + 6x - 42] = -[x*(x - 7) + 6*(x - 7)] = -(x - 7)*(x + 6)
How do you factor 4x4 plus 34x plus 42?
You cannot factor 4x4 + 34x + 42 The expression has a minimum value of approx 9.21616 when x = -1.286 (= 0.5*cuberoot(17). Since the expression is always positive, it does not cross the x-axis and so does not have any real roots. Consequently, it does not have any real factors.
