Expand the polynomial: (6x^2−11y^3)(−6x^2−11y^3)

on expanding polynomial (6x^2−11y^3)(−6x^2−11y^3) or is .

Step-by-step explanation:

We have , (6x^2−11y^3)(−6x^2−11y^3):

⇒

We know that :

⇒

⇒

⇒

⇒

Therefore, on expanding polynomial (6x^2−11y^3)(−6x^2−11y^3) or is .

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the answer will be b x² +x-1
