How do I do Slope Intercept Form Step to Step? PLEASE HELP!

Use the x-intercept method to find all real solutions of the equation.x^3-10x^2+27x-18=0

Josephine has a great garden with and area of 2x2 + x - 6 square feet

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
