Find the product of x^2+6x-5 and -3x+2

3x^3 -16x^2 +27x -10

Step-by-step explanation:

(x^2+6x-5) (-3x+2) = -3x(x^2+6x-5)+2(x^2+6x-5) = -3x^3 -18x^2 +15x + 2x^2+12x-10 = -3x^3 -18x^2 +2x^2+15x+12x-10 = -3x^3 -16x^2 + 27x -10

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
