Use the graph to write the factorization of x^2+4x-5
Accepted Solution
A:
Answer: OPTION CStep-by-step explanation: By definition, the roots of the quadratic function are the interceptions of the parabol with the x-axis. As you can see in the graph, the parabola intersects the x-axis at: [tex]x=-5\\x=1[/tex] Then these are the roots. Therefore, this means that: [tex]x=-5\\x+5=0\\\\x=1\\x-1=0[/tex] So, the factorization is the following: [tex](x+5)(x-1)=0[/tex]
