End.
Step (1)
x²+7x8=0
Step (2)
(+8)(x - 1) = 0
Step (3)
*+8 = 0 or 1-1=0
Step (4)
8 or
X-1
a. The solution is incorrect. Identify the step that does not follow logically from
the previous step. Explain why it is incorrect.
A the last step is incorrect because X+8=0 is not equal to 8 it is equal to
-8
b. Solve the quadratic equation correctly using any method, and show that
your solution(s) are correct
