factor of k²-12k-64
pls answer my question.pls pls pls
Answers
Answer:
The first term is, k2 its coefficient is 1 .
The middle term is, -12k its coefficient is -12 .
The last term, "the constant", is -64
Step-1 : Multiply the coefficient of the first term by the constant 1 • -64 = -64
Step-2 : Find two factors of -64 whose sum equals the coefficient of the middle term, which is -12 .
-64 + 1 = -63
-32 + 2 = -30
-16 + 4 = -12 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -16 and 4
k2 - 16k + 4k - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
k • (k-16)
Add up the last 2 terms, pulling out common factors :
4 • (k-16)
Step-5 : Add up the four terms of step 4 :
(k+4) • (k-16)
Which is the desired factorization
Answer:
factor of this equation will be 16 amd 4
