factorise 49x^2-35x+6
Answers
Answer:
-294 + 1 = -293
-147 + 2 = -145
-98 + 3 = -95
-49 + 6 = -43
-42 + 7 = -35
-21 + 14 = -7
-14 + 21 = 7
-7 + 42 = 35 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and 42
49x2 - 7x + 42x - 6
Step-4 : Add up the first 2 terms, pulling out like factors :
7x • (7x-1)
Add up the last 2 terms, pulling out common factors :
6 • (7x-1)
Step-5 : Add up the four terms of step 4 :
(7x+6) • (7x-1)
Which is the desired factorization
