4. Find the solutions of each of the following QE by factoring. Explain how you arrived at your answer.

a. (x+3)^2 = 25 c. (2t - 3)^2 = 2t^2 + 5t - 26

b. (s+4)^2 = -2s d. 3(x+2)^2 = 2x^2 + 3x - 8

5. Do you agree that x^2 + 5x - 14 = 0 and 14 - 5x - x^2 = 0 have the same solutions? Justify your answer.

6. Show that the equation (x - 4)^2 = 9 can be solved both by factoring and extracting square roots.

7. A computer manufacturing company would like to come up with a new

laptop computer such that its monitor is 80 sq inches smaller than the

present ones. Suppose the length of the monitor of the larger computer

is 5 inches longer than its width and the area of the smaller computer

is 70 sq inches. What are the dimensions of the monitor of the larger

computer?

THANK YOU PO :)
