Question

n²/2 - 25n/2 + 50 = 0
Do middle term factorization. ​

Answer 1

Answer:   1

:

Trying to factor by splitting the middle term

1.1 Factoring n2-41n+400

The first term is, n2 its coefficient is 1 .

The middle term is, -41n its coefficient is -41 .

The last term, "the constant", is +400

Step-1 : Multiply the coefficient of the first term by the constant 1 • 400 = 400

Step-2 : Find two factors of 400 whose sum equals the coefficient of the middle term, which is -41 .

-400 + -1 = -401

-200 + -2 = -202

-100 + -4 = -104

-80 + -5 = -85

-50 + -8 = -58

-40 + -10 = -50

-25 + -16 = -41 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -25 and -16

n2 - 25n - 16n - 400

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

n • (n-25)

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

16 • (n-25)

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

(n-16) • (n-25)

Which is the desired factorization
