Which shows the equation below written in the form
x2 + 7 x + 9 = 3

Step-by-step explanation:

x^2 +7x+6=0

(x+1)(x+6)=0

x=－1 x=－6

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 is a i belaeve atleast thats what my calculator just gfave me
