How many points will the graph of x^2+2x+1 will cut the x-axis?(a) 3(b) 1(c) 2(d) 0The question was asked in my homework.I need to ask this question from Geometrical Meaning of Zeros of Polynomial in chapter Polynomials of Mathematics – Class 10

Answer» RIGHT OPTION is (d) 0

To elaborate: The graph of x^2+2x+1 does not CUT the x-axis, because it has IMAGINARY roots.

x^2+2x+1=0

x^2+x+x+1=0

x(x+1)+(x+1)=0

(x+1)(x+1)=0

x=-1, -1
