Express the Sides of a Rectangle: Mathematical Representation Problem

Question

Express the sides of the given rectangle.

00:00 Express the sides of the rectangle

00:03 We'll use the formula for calculating rectangle area (side times side)

00:08 We'll use a trinomial to factor, identifying the coefficients

00:16 We want to find two numbers whose sum equals B

00:24 and their product equals C

00:34 These are the matching numbers

00:38 We'll put them in parentheses, this is the product of the sides

00:43 And this is the solution to the question

$x+1,x+2$
