Solve the quadratic equation by using either a numeric or a graphic approach.
- 14x-49-0
a x = -11.1 or x = -12
c. x = 16.9 or x = -2.
b. x = 12.3 or x = -10.82
d. x = 1 or x = -3
select the best answer from the choices provided

we need the options

step-by-step explanation:

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 first one, all those points on the line just make a strait line.
