Step by Step Solution
Step 1 :
Equation at the end of step 1 :
((22•32r2) - 12r) + 1
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 36r2-12r+1
The first term is, 36r2 its coefficient is 36 .
The middle term is, -12r its coefficient is -12 .
The last term, "the constant", is +1
Step-1 : Multiply the coefficient of the first term by the constant 36 • 1 = 36
Step-2 : Find two factors of 36 whose sum equals the coefficient of the middle term, which is -12 .
| -36 | + | -1 | = | -37 | ||
| -18 | + | -2 | = | -20 | ||
| -12 | + | -3 | = | -15 | ||
| -9 | + | -4 | = | -13 | ||
| -6 | + | -6 | = | -12 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and -6
36r2 - 6r - 6r - 1
Step-4 : Add up the first 2 terms, pulling out like factors :
6r • (6r-1)
Add up the last 2 terms, pulling out common factors :
1 • (6r-1)
Step-5 : Add up the four terms of step 4 :
(6r-1) • (6r-1)
Which is the desired factorization
Multiplying Exponential Expressions :
2.2 Multiply (6r-1) by (6r-1)
The rule says : To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (6r-1) and the exponents are :
1 , as (6r-1) is the same number as (6r-1)1
and 1 , as (6r-1) is the same number as (6r-1)1
The product is therefore, (6r-1)(1+1) = (6r-1)2
Final result :
(6r - 1)2
