How many points will the graph of x2+ 2x + 1 will cut the x-axis?a)3b)...
The graph of x2 + 2x + 1 does not cut the x-axis, because it has imaginary roots.
x2 + 2x + 1 = 0
x2 + x + x + 1 = 0
x(x + 1) + (x + 1) = 0
(x + 1)(x + 1) = 0
x = -1, -1
x2 + 2x + 1 = 0
x2 + x + x + 1 = 0
x(x + 1) + (x + 1) = 0
(x + 1)(x + 1) = 0
x = -1, -1

How many points will the graph of x2+ 2x + 1 will cut the x-axis?a)3b)...
Explanation:
The given equation is x^2 + 2x + 1 = 0.
To find the number of points at which the graph cuts the x-axis, we need to find the number of distinct real solutions to the equation.
Using the quadratic formula, we can solve the equation for x:
x = (-b ± √(b^2 - 4ac)) / (2a)
In this case, a = 1, b = 2, and c = 1. Substituting these values into the quadratic formula:
x = (-2 ± √(2^2 - 4(1)(1))) / (2(1))
x = (-2 ± √(4 - 4)) / 2
x = (-2 ± √0) / 2
Since the discriminant (√(b^2 - 4ac)) is zero, there is only one solution for x. Thus, the graph of the equation x^2 + 2x + 1 = 0 does not cut the x-axis.
Therefore, the correct answer is option 'D' which states that the graph cuts the x-axis at 0 points.
