Quadratic Equations Examplesof quadratic equations: `2x^2 + 3x − 5 = 0` `x^2 − x − 6 = 0` `x^2 = 4` Therootsof an equation are thex-values that make it "work" We can find the roots of a quadratic equation either by using the quadratic formula or by factoring. ...
A polynomial is defined by the coefficients array, which can be real or complex numbers. The first coefficient belongs to the highest degree term; the last one is the constant term. The number of coefficients automatically defines the polynomial degree. If your polynomial misses a term, just se...

When I calculated it with a hand calculator, it turned out to be exactly 44. And indeed, when I substitute x=4x=4 into the original equation, it is a solution. So this appears to be true: 2+11i−−−−−√3+2−11i−−−−−√3=42+11i3+2−11i3=4 So we ha...
