Question Expand the expression (x+6)(x+5)(x+6)(x+5) and illustrate the resulting product as a rectangle.

Studdy Solution

STEP 1

Assumptions
1. We are asked to complete a rectangle to illustrate the product of two binomials, (x+6)(x+6) and (x+5)(x+5).
2. The rectangle will be divided into smaller rectangles or squares, each representing a term from the expansion of the product.
3. The length and width of the rectangle will correspond to the terms in the binomials.

STEP 2

To illustrate the product of (x+6)(x+6) and (x+5)(x+5) as a rectangle, we will draw a rectangle and divide it into parts that represent each term in the product.

STEP 3

The first term of each binomial, xx, will represent one dimension of the rectangle. The second terms, 66 and 55, will represent the other dimension.

STEP 4

Draw a rectangle and label one side with x+6x+6 and the adjacent side with x+5x+5.

STEP 5

Divide the rectangle into four smaller parts by drawing a line parallel to the side labeled x+5x+5 at a distance of 66 units from it and another line parallel to the side labeled x+6x+6 at a distance of 55 units from it.

STEP 6

Label the four smaller rectangles/squares that result from the division. The top left square will be x×xx \times x, the top right rectangle will be x×5x \times 5, the bottom left rectangle will be 6×x6 \times x, and the bottom right rectangle will be 6×56 \times 5.

STEP 7

Write the area of each smaller rectangle/square inside them, corresponding to the product of their sides. The top left square will have an area of x2x^2, the top right rectangle will have an area of 5x5x, the bottom left rectangle will have an area of 6x6x, and the bottom right rectangle will have an area of 3030.

STEP 8

The completed rectangle now illustrates the product (x+6)(x+5)(x+6)(x+5) with each part of the rectangle representing a term in the expanded form of the product.

STEP 9

The expanded form of the product can be found by adding the areas of all the smaller rectangles/squares.

STEP 10

Write down the expanded form using the areas of the smaller parts:
x2+5x+6x+30x^2 + 5x + 6x + 30

STEP 11

Combine like terms in the expanded form to simplify the expression.
x2+(5x+6x)+30x^2 + (5x + 6x) + 30

STEP 12

Calculate the sum of the like terms 5x5x and 6x6x.
5x+6x=11x5x + 6x = 11x

STEP 13

Write the final simplified form of the expanded product.
x2+11x+30x^2 + 11x + 30
The rectangle illustrates the product (x+6)(x+5)(x+6)(x+5) and its expansion is x2+11x+30x^2 + 11x + 30.
