Webb17 nov. 2015 · To solve a system of linear equations that are both in standard form, the most efficient method to use would be the "elimination method". To carry out elimination, you need to alter one (or both) of the equations so as to have one of the variables (and their coefficient) match the same one in another equation. In your example, you have: 1) 5a + … WebbSoluciona tus problemas matemáticos con nuestro solucionador matemático gratuito, que incluye soluciones paso a paso.

Whereas a2 − b2 = (a + b)(a − b) is very simple, to factor a2 +b2 requires the use of complex numbers. So a2 +b2 = (a +ib)(a −ib), but there is no other factoring with real number coefficients. a2 +b2 doesn't have a nice factorization over the reals, but over the complex numbers it's the squared magnitude of a + bi, which gives ... shulan holmes-farley
