The factor of quadratic polynomial
Answer to Problem 22CLR
Explanation of Solution
Given information:
Calculations: We have
We need to compare given quadratic with standard quadratic
Then we need to get the values of a, b and c and apply product
On comparing given quadratic
Product of value of a and c =
Value of
Now, we need to get two factors of -42 those add upto
We could see
So, split middle term
Now, making it into two groups and factor out Greatest Common Factor (GCF) of each group
Factor out Greatest Common Factor (GCF)
Factor out the common parenthesis
Therefore, the factors of
