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...

A rhetorical question is a question you ask someone, but you do not expect or need an answer. Often you know the answer to the question already. They are often used in emotive writing to emphasise particu...

(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=-...

Systematic sampling refers to a way of choosing participants for a study by taking a list of all participants in a population and choosing every nth number from the list. For example, every 10th or 15th p...
