3y-1=2y+4To find out what "y=" we need to get all the y values on one side of the equation, and the other numbers on the other side of the equation. We can do this by simply adding or subtractin...

any odd number can be written as (2n+1), where n is any integer (whole number). Squaring any odd number is therefore= (2n+1)² . expanding the brackets gives =4n²+2n+2n+1² ...

On a straight line graph, the lines are formed by an equation in the form y=mx + c. The m value in this equation represents the gradient, and the c value is the y-intersect.If t...

x = 5

To expand this we multiply the first term in each bracket together to get x² Then we do the first bracket's first term by the second bracket's second term to get -5x The we do the first bracke...
