Notes and examplesFind (4x2 – 18x) ÷ 2x Find (2y2 – 3y – 9) ÷ 3y

Find (48z2 + 18z) ÷ 6z Find (–8x2 + 6x – 28) ÷ 4x

Notes and examplesFind (2r2 + 5r – 3) ÷ (r + 3). Find (2c2 – 3c – 9) ÷ (c – 3).

Find (x2 + 7x – 15) ÷ (x – 2) by using long division

Find (y2 – 4y + 5) ÷ (y – 3) by using long division

Notes and examplesGEOMETRY The area of a rectangle is represented by 3x + 90. Its length is (x – 3).Find (3x + 90) ÷ (x – 3) to determine the width of the rectangle.

GEOMETRY The area of a triangle is represented by 8x + 21. The height is 2x + 3. Find 2(8x + 21) ÷ (2x + 3) to find the base of the triangle.

Notes and examplesFind (x3 – 34x + 45) ÷ (x – 5). Find (b3 – 6b2 + 32) ÷ (b – 4).
