Answer:
Step-by-step explanation:
The first term is, y2 its coefficient is 1 .
The middle term is, -6y its coefficient is -6 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 1 • 5 = 5
Step-2 : Find two factors of 5 whose sum equals the coefficient of the middle term, which is -6 .
-5 + -1 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and -1
y2 - 5y - 1y - 5
Step-4 : Add up the first 2 terms, pulling out like factors :
y • (y-5)
Add up the last 2 terms, pulling out common factors :
1 • (y-5)
Step-5 : Add up the four terms of step 4 :
(y-1) • (y-5)
Which is the desired factorization
