X – 6x² + 3x - 18=0 What is the only value of x that is a real solution to the
equation shown above?

  x=6

Step-by-step explanation:

The equation ...

can be factored by grouping to get a linear factor and a quadratic factor. The linear factor always has a real zero. This quadratic factor does not.

The one real solution is x=6, the value of x that makes (x-6) = 0.

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
