find the vertex..y=x(x+7)
To find the vertex of the quadratic equation y = x(x + 7), you can use the vertex formula. The vertex formula states that for a quadratic equation in the form y = ax^2 + bx + c, the x-coordinate of the vertex can be found using the formula x = -b/(2a), and then substitute this value back into the equation to find the y-coordinate.
In this case, we have y = x(x + 7), where a = 1, b = 0, and c = 0.
To find the x-coordinate of the vertex:
x = -b / (2a)
= -0 / (2*1)
= 0
To find the y-coordinate of the vertex, substitute the x-coordinate into the equation:
y = 0(0 + 7)
= 0
Therefore, the vertex of the quadratic equation y = x(x + 7) is (0, 0).
