2.把后面一个式子改写成3X-2Y+C/2=0这样看来方便一点要平行:显然A=3 但是C/2≠-1 C≠-2要相交:因为平面内两直线不是相交就是平行.所以就是不平行,就是A≠3 C可以任意取要垂直:方法很多,这里用一法向量相互垂直的原理.(A,-2)·(3,-2)=0 A=-3/4.垂直也是相交的一种情况,所以...

y=3x2-4 (1) y=2x+3 121 0=(3x2-4)-(2x+3)(2)-(1) This equation simpoifes to 0=3x^2-2x-7 which dass not factorise, so we need to use the quadratic formula to find the two possible ualces of x. x=(-b±√(b^2-4ac))/(2a)=\frac(-(-2)±√((22)^2-48*(-7))...
