Answer 2

n^2-n-2=0

Factoring n2-n-2

The first term is, n2 its coefficient is 1 .

The middle term is, -n its coefficient is -1 .

The last term, "the constant", is -2

Step-1 : Multiply the coefficient of the first term by the constant 1 • -2 = -2

Step-2 : Find two factors of -2 whose sum equals the coefficient of the middle term, which is -1 .

-2 + 1 = -1 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and 1

n2 - 2n + 1n - 2

Step-4 : Add up the first 2 terms, pulling out like factors :

n • (n-2)

Add up the last 2 terms, pulling out common factors :

1 • (n-2)

Step-5 : Add up the four terms of step 4 :

(n+1) • (n-2)

Which is the desired factorisation

Equation at the end of step

1

:

(n + 1) • (n - 2) = 0
