What are the factors of the quadratic trinomial 8x2 plus 2x-1?
8X^2 + 2X - 1 = 0 need quadratic formula -b +/- sqrt(b^2-4ac)/2a a = 8 b = 2 c = -1 -2 +/- sqrt(2^2 -4(8)(-1))/2(8) -2 +/- sqrt(4 + 32)/16 -2 +/- sqrt(36)/16 (-2 +/- 6)/16 X = 1/4 X = -1/2 My TI-84 confirms this answer

How do you factor 18x plus 12x2 plus 2x3?
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (8 plus or minus the square root of 10) divided by 3 x = 3.720759220056127 x = 1.6125741132772067
What are the factors of this quadratic equation 8x2 plus 2x -1?
8x2 + 2x - 1 = 8x2 + 4x - 2x - 1 = 4x(2x + 1) - 1(2x + 1) = (4x - 1)(2x + 1)

8X^2 + 2X - 1 = 0 need quadratic formula -b +/- sqrt(b^2-4ac)/2a a = 8 b = 2 c = -1 -2 +/- sqrt(2^2 -4(8)(-1))/2(8) -2 +/- sqrt(4 + 32)/16 -2 +/- sqrt(36)/16 (-2 +/- 6)/16 X = 1/4 X = -1/2 My TI-84 confirms this answer
What is the factor 2x3-8x2 plus 6x?
What are the factors? 2x3 - 8x2 + 6x = 2x(x - 1)(x - 3).
Factor of the trinomial 8x2 -12x - 8?
8x2 - 12x - 8 = 4 (2x2 - 3x - 2) = 4 (2x2 + x - 4x - 2) = 4 (x (2x + 1) - 2 (2x + 1)) = 4 (x - 2) (2x + 1).
8x2 - 8x - 16?
Simplifying 8x2 + -8x + -16 Factor out the Greatest Common Factor (GCF), '8'. 8(x2 + -1x + -2) Factor a trinomial. 8((-x + -1)(-x + 2)) Final result: 8(x - 2)(x + 1)

How do you identify the polynominal by name and degree of -8x2 -2x 8?
-8x2 - 2x + 8 this is a quadratic equation or a second order polynomial it is a second order polynomial because it has a term in x2 For every polynomial we name it according to the highest power term in the equation.......
How do you add quadratic equations?
You add compatible terms together. For example, if one equation has 3x2, and the other has 5x2, you combine those two terms as 8x2.
What is the answer to -4x2 minus 32x plus x plus 8 equals 8x2 minus 56x?
-4x2 - 32x + x + 8 = 8x2 - 56x : simplify and group the various terms-32x + 56x + x + 8 = 8x2 + 4x225x + 8 = 12x2 : Now present this as a standard quadratic equation.12x2 - 25x - 8 = 0 : Solving for the roots of a quadratic equation gives :-x = [25 ± √(252 + 4x12x8)] ÷ 2x12 = [25 ± √1009] ÷ 24 = [25 ± 31.765] ÷ 24x = 56.765/24 = 2.365 and x = -6.765/24 = -0.282x = 2.365 and -0.282
What is the factorization of the trinomial 8x2-14x-15?
(x + 2)(x - 7)
What are the factors of 8x squared plus 6x minus 9?
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
