There are no integers that work.

Use the distributive property:

4x(3x - 4) + 8x

4x(3x) - 4x(4) + 8x

12x² - 16x + 8x

Combine like terms:

12x² - 8x

x = [-b ±√(b² - 4·a·c)] / (2·a)

When  x²  =  150     --->     x  =  ± √(150)     --->     x  =  ± √(25)√(6)  =  ± 5√(6)

You can use trigonometry.

If you know the values of the opposite side and the hypotenuse:  Angle  =  sin^-1(opposite/hypotenuse).

If you know the values of the adjacent side and the hypotenuse:  Angle  =  cos^-1(adjacent/hypotenuse).

If you know the values of the opposite side and the adjacent side:  Angle  =  tan^-1(opposite/adjacent).

There are no real numbers that when added together give you -11 but when they are multiplied give you -60.

i  =  √(-1)

(9x⁴)(4xy)  =  (9)(4)(x⁴)(x)(y)  =  36x⁵y

If you want a formula to find a particular term (say term 'x'), you can use this formula:

To find F₁₂, replace x with 12 in the above formula.
