You can put this solution on YOUR website!
Given: x=3 & x=-5
It follows ----------> (x-3)(x+5)=0
Then expand, x^2-3x+5x-15=0
highlight(x^2+2x-15=0), ANSWER
See graph:
drawing(400,400,-7,7,-20,7,grid(1),graph(400,400,-7,7,-20,7,x^2+2x-15))------> See it passes thru points (3,0) & (-5,0)
.
Thank you,
