Learning Task 4. Read carefully the

A. Factor the following completely.

1. x² - 25 = (x - 5)(x + 5)

2. 2x² –15x –8 = (x - 8)(2x + 1)

3. 3x² + 30x + 75 = 3(x + 5)²

5. 5x³ - 5x² -10x = 5x(x - 2)(x + 1)

4. x³ - 27 = (x - 3)(x² + 3x + 9)

B. Solve the following problems.

1. If the area of the rectangle is given by the polynomial 2x2 - 7x - 15, what is the dimension of the rectangle in terms of x? (2x+3)(x-5)=2x²-7x-15

2. The volume of the prism is x3 + 64. If the height is the binomial factor of the volume and the trinomial factor is the product of length and width, find the height of the prism. x - 4

3. The length of a rectangular lot is 6 less than thrice its width, If the area is 45 square cm, What is the length and the width of the rectangle? The length of the rectangle lot is 9 cm and its width is 5 cm.
