1.Use the quadratic formula to prove that the roots of such an equation must have -a/b as their sum and a/c as their product.
2.Prove that the sum of the squares of the roots of such an equation is a/b-2ac. (Hint): Consider (r1+r2). Derive an expression for r1+r2 from this.)

1.用二次定理证明对于这个方程式的平方根必须含有-a/b作为它们的和,a/c作为他们的乘积
2.证明这个方程的平方根的平方是a/b-2ac,(提示):考虑(r1+r2).从一个关于r1+r2的表达式得出

1. 请用一元二次函数公式证明这样一个算式的两个解的和必须是-a/b,积必须是a/c.
2. 证明这样一个算式的两个解的平方的和是a/b-2ac (提示: r1+r2,为r1+r2推理出一个式子.)

1.Use二次公式,证明了这种方程根必须检查时,其金额和a / c作为他们的产品。

2.Prove这的这样一个方程根的一个/ b-2ac。(提示):考虑(r1 + r2)。获得一个表达式为r1 + r2。)

用平方公式证明等式的根之和为-a/b,之积为a/c
证明等式的平方之和等于a/b-2ac.(提示:考虑r1+r2,将表达式除以r1+r2)

1用公式法证明这样等式的根之和是-a/b,之乘机是a/c。
2证明两根平方之和是a/b-2ac。
提示: 考虑(r1+r2)。推算出关于r1+r2的表达式。
差不多就这个意思了,quadratic formula实在想不起中文是什么了,应该是公式法(二元一次方程求根公式)
希望你满意。。...

1.使用二次公式证明一元二次方程两根之和必为-a/b,且两根之积必为a/c。
2.证明:方程式的根的平方和是 a/b-2ac。(提示:考虑r1+r2。从中得到一个关于r1+r2的表达式)
