When the coefficient of ( x^2 ) is negative in a quadratic equation, the parabola opens downward. This means that the vertex of the parabola represents a maximum point, and the value of the function decreases on either side of the vertex. Consequently, the graph will touch or cross the x-axis at most twice, indicating that the quadratic can have zero, one, or two real roots.
If the coefficient of x2 is positive then the parabola is cup shaped (happy face). If the coefficient of x2 is negative then the parabola is cap shaped (gloomy face).

In the form y=mx+b, b is the y-intercept and m is the coefficient, so if an equation has a negative coefficient, m<0. As a graph, the slope of the line is negative.
It is like the letter U.
-x times -x = x2 (negative multiplied with negative = positive) sqrt of x2 = x
If the coefficient of x2 is positive then the parabola is cup shaped (happy face). If the coefficient of x2 is negative then the parabola is cap shaped (gloomy face).
A parabola opens upwards if the quadratic coefficient - the number before the "x2" is positive; downward if it is negative. Note that x2 is the same as 1x2.
The coefficient of x2 is -3 which is negative. Therefore the curve is downward opening.
A coefficient is a number in front of a variable (i.e. multiplied by it).For example, in the expression x2 - 10x + 25, the coefficient of x2 is 1 and the coefficient of x is -10. The third term, 25, is a constant.If the expression were -x2 + 10x + 25, the coefficient of x2 would be -1, and the coefficient of x would be 10.
Yes, a coefficient of a variable can be negative.
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.

The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
negative 'temperature coefficient of reactivity'
No, it will be entirely above the x-axis if the coefficient of x2 > 0, or entirely below if the coeff is <0.

The Hall coefficient has the same sign as the charge carrier. The charge carrier in a normal electric current, the electron, is negative, and as a result the Hall coefficient is negative.
