Lesson 1 |
Problem: Solve for x: x2 + 3x + 2 = 0
Solution x2 + 3x + 2 = 0; x2
+ 2x + x + 2 = 0 ;
Step 1:
Solution x(x + 2) + 1 (x + 2) = 0; (x + 1)(x + 2) = 0;
Step 2:
Solution x + 2 = 0; x = -2, x + 1 = 0; x = -1
Step 3:
Solution Answer: -2, -1
Step 4:
Complete
Try two practice problems:
A. x2 + 6x + 9 = 0
B. x2 - 36 = 0
