IB数学改革,AA中加入了不少有趣的知识点,下面是多项式理论中关于高次韦达定理的习题解答,都是学生问的,然后整理了一下,以便帮助其他有需要的学生。 Question 1-Exercise 5I-8【详解】 不妨假设公共解为 x_0 ,…
In short if Product of roots>0 and Sum of roots>0, then we have a non-negative root as desired. If the product of the roots is negative, then that means there is one positive root and one negative root, so we have what we need. In short if Product of roots...
The sum of the roots of 2x2 + 6x- a = 0 is the same as the product of theroots of 3x2 + bx + 1 = 0.The product of the roots of 2x2 + 6x - a = 0 isthe same as the sum of the roots of3x^2+bx+1=0 Find the value of ab. ...

Planting helps prevent soil erosion since the roots of the plants help keep the soil together. Growing vegetation around your residence keeps you nourished and healthy, along with the surrounding. Enjoyable Aerobic Exercise Working in your home garden is an excellent way to enjoy aerobic exercise. ...

Microbes, not plant material, are the key to building organic matter. Studies indicate soil organic matter accumulates from inputs of dead microbial cells and microbial by products formed when microbes eat plant roots and residues, rather than from plants themselves, as previously thought. Soil orga...
