WebbWe could obtain a formula using the known algebraic identity (a+b) 2 = a 2 + b 2 + 2ab. On subtracting 2ab from both the sides we can conclude that a2 + b2 = (a +b)2 - 2ab. Similarly, we can also say that, a2 + b2 = (a - b)2 + 2ab. WebbAll equations of the form ax^{2}+bx+c=0 can be solved using the quadratic formula: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. The quadratic formula gives two solutions, one when ± is … Webb当 a=2 时,原式=23+3×2=14.
