The second step in the process for factoring the trinomial x^2-3x-40 is to

Second step  x( x +5 ) -8 (x+ 5 ) in process of factoring .

Step-by-step explanation:

Given : Trinomial x²-3x-40 .

To find : The second step in the process for factoring .

Solution : We have x²-3x-40 .

On factoring x²+ 5x - 8x - 40 .

Taking common x from first two terms and -8 from last two terms.

x( x +5 ) -8 (x+ 5 ) .

Therefore , Second step  x( x +5 ) -8 (x+ 5 ) in process of factoring .

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

there still no table
