Whole question is solve for x: (x+4)/2=7

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

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
