Factor 5z^3+34z^2+53z-12 given that z+3 is a factor

Do a long division 
the quotient comes to 

5z^2 + 19z - 4

this factors to

(5z - 1)(z + 4)

so factors are (z+3)(z+4)(5z-1)

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
