athe standard quadratic equation, where we can now allow the coefficients b and c to be negative. Also, generalize this further to the most general form of the quadratic equation: ax2+ bx + c = 0. 标准二次方程,我们可以现在允许系数b和c是消极的地方。 并且,进一步推断这对二次方程的最一般...
aand habitat use efficiency 并且栖所用途效率[translate] aWe can rewrite this as (5 – x)2= 25 – 21, or as (5 – x)2= 4, or finally, by taking square roots, as 5 – x = 2. It follows that x =3 is the solution to our quadratic equation. 我们可以重写此,当 (5 - x) 2...
