Step by Step Solution
Step 1 :
Equation at the end of step 1 :
(32x2 - 6x) + 1
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 9x2-6x+1
The first term is, 9x2 its coefficient is 9 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is +1
Step-1 : Multiply the coefficient of the first term by the constant 9 • 1 = 9
Step-2 : Find two factors of 9 whose sum equals the coefficient of the middle term, which is -6 .
-9 | + | -1 | = | -10 | ||
-3 | + | -3 | = | -6 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and -3
9x2 - 3x - 3x - 1
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (3x-1)
Add up the last 2 terms, pulling out common factors :
1 • (3x-1)
Step-5 : Add up the four terms of step 4 :
(3x-1) • (3x-1)
Which is the desired factorization
Multiplying Exponential Expressions :
2.2 Multiply (3x-1) by (3x-1)
The rule says : To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (3x-1) and the exponents are :
1 , as (3x-1) is the same number as (3x-1)1
and 1 , as (3x-1) is the same number as (3x-1)1
The product is therefore, (3x-1)(1+1) = (3x-1)2
Final result :
(3x - 1)2
