Use the x-intercept method to find all real solutions of the equation. x- 11x2 +312-21 - 0
a. X=-1, -3, or -7
c. x= 1, 3, or 7
b. x = 1, 3, or -7
d. x=-1, - 3, or 7

Which polynomial function has x intercepts -1, 0, and 2 and passes through the point (1, -6)

Which of the following is true for the relation f(x)=2x^2+1

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
