Dakarai wrote the system of linear equations below. 7x+8y=28 -3x+9y=-24 dakarai then wrote the coefficient matrix that represents this system. which matrix could she have written?

Step-by-step explanation:

Find the attachment below for answer and explanation.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
