Using the factor to solve the quadratic equation Check by substition or by using a graphing utility and identifying x- intercepts x to the second power minus five x minus thirty-six equals zero?

Answer 1

Well, your wording is a little off, but I think you are asking to solve the equation using the Quadratic Formula, equation being 0=x^2 - 5x - 36

a=1

b=-5

c=-36

5±√-5^2 - 4(-36)/2

5±√-25+144/2

5±√119/2

5±10.9/2

5+5.45 or 5-5.45

approximately 10.45 or -0.45
