Question

(D^2-5D-6)y=0
find
C.F​

Answer 1

Answer:

D=3

D=2

Y=0

Step-by-step explanation:  

step 1: multiply the coefficient of the first term by the constant 1.. 6=6

step  2: find the factor of 6 whose sum equal the coefficient  of the middle terms, which is -5.

-6  +  -1  =  -7

-3   +   -2  =  -5 that's it

step  3: rewrite the polynomial spitting the middle terms using the two factors found in step 2 above -3 and -2

d ki power 2 -3d -2d -6

step 4: add up the first 2 terms pulling out like factors

d.. (d-3)

add up the last 2 terms pulling out common factors

2.. (d-3)

step 5: add up four terms of step 4

(d-2)... (d-3)
