I love how this channel explains everything clearly and step by step so you can understand exactly how to answer these questions, and also why you do a certain step. This channel is slowly clearing up all the doubts I have about certain topics!

something that I realised is that whenever the sign is greater than/ greater or equals to we'll always have two solutions one here x....
@1stClassMaths7 ай бұрын
That is correct unless the quadratic is -x^2 in which case it will be the other way as the graph will go the other way too.

1) if original equation is less 0 and x is positive then we highlight the below part of graph 2) If orignal equation is less 0 but x is negative than we highlight the legs above the line graphs 3) if original equation is greater than 0 and x is positive we highlight the upper legs of the graph 4) if original equation is greater than 0 but x is negative then we highlight the lower part below line graph

How did you sketch the graph without finding out the turning point?
@1stClassMaths27 күн бұрын
The turning point isn't needed for this sketch as we are only interested in the roots, where it crosses the axes. For a true sketch sure you might want to plot the coordinates but it isn't needed for this.

what about if there was a number infront of the x in the inequality?
