The roots of the function f(x) = x2 – 2x – 3 are shown. What is the missing number? x = –1 and x =

x=3

Step-by-step explanation:

factoring

set to 0

no not all of them.

step-by-step explanation:

some of them have a square base.

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
