Rewrite the solution in the first box. Write your solution in the second box. In the third box, write your explanation on how your solution corrects the original one.
Problem 1:
Explanation:
The proper way to factor
36 - x²
= -x² + 36
= - (x + 6)(x - 6)
= (6 - x)(6 + x)
The proper way to factor
x² - 6x
= x(x - 6)
The proper way to factor (sign convention)
Problem 2:
Explanation:
The proper way to factor and simplify (careful on the sign)
2a - 3(a - 5)
= 2a - 3a + 5
= - a + 5
Problem 3:
Short Method Solution:
Another Method for Solution:
Explanation:
at the last part, the first box still simplify the final answer to which cannot be simplified anymore.
this should be the final answer
Problem 4:
Explanation:
The proper way to factor
b² - 4b + 4
= (b - 2)(b - 2)
Lesson Learned:
One must be careful about factoring, simplifying and designating the sign if positive or negative, one mistake on placing sign would make a huge difference on the solution.
