2x²+6x-3=0To begin, we need to make sure x² is by itself, meaning that we divide the whole equation by 2. So from here we get (2x²+6x-3=0) / 2 = x²+3x-3/2=0. No...

(x+3)(x+2)=F=xx= x^2O=x2=2xI=3x=3xL= 3*2=6=x^2 + 2x + 3x + 6= x^2 + 5x + 6

3x+2y=8 (1)2x+5y=-2 (2)So you need to have a common multiple of either x or y in this example I’ll equate the x of both equations so I’ll multiply (1) by 2 and (2) by 3 2( 3x+2y=8). 6x+4y=16 (3).3(2x+5y=-...

x= (3 + ln(11))/4

Hi there, this is a common confusion so don't worry.
It is helpful to write out a number line when differentiating and drawing an arrow to show which way the power is moving.
