Question

Factorise 4x⁴-y⁴ step by step instructions

Answer 1

Answer:

mn+m+n+1

Factorization found :

(m + 1) • (n + 1)

Trying to factor a multi variable polynomial :

1.1 Split mn + m + n + 1

into two 2-term polynomials

+ m + mn and + n + 1

This partition did not result in a factorization. We'll try another one:

mn + m and + n + 1

This partition looks good

1.2 Pull out from each binomial separately

mn + m = m • (n + 1)

+ n + 1 = + 1 • (n + 1)

1.3 Add up to arrive at the desired factorization

(m + 1) • (n + 1)

Factorization found :

(m + 1) • (n + 1)
