Frequently Asked Questions

How do you identify difference of two squares?

a^2 - b^2 equals (a+b) (a-b) In mathematics, the difference of two squares is a squared (multiplied by itself) number subtracted from another squared number. Every difference of squares may be factored according to the identity. a 2 − b 2 = ( a + b ) ( a − b ) {displaystyle a^ {2}-b^ {2}= (a+b) (a-b)}

How do you use the difference of two squares?

Difference of Two Squares Formula. The trick to factorising the difference of two squares is to use the formula, textcolor{blue}{a^2 -b^2 = (a+b)(a-b)} This can be used in either direction to factorise or expand such expressions quickly. To show that this works, we will expand the two brackets of the general formula.

Can 2 different size squares have the same perimeter?

In general, figures with longer perimeters have larger areas. If two rectangles have different perimeters, the one with the larger perimeter will have a larger area. If two squares have different perimeters, the one with the larger perimeter will have a larger area. If two polygons have the same perimeter, then they must have the same shape.
