What is the discriminant in x squared equals 11x?
The discriminant, for what it is worth in an example such as this, is 11.
Why is it that the parabolas of y equals x squared -4x plus 8 and y equals 8x -14 - x squared can never intersect with each other giving reasons why not?
Because when collated together the discriminant of b2-4ac = -32 i.e. 144-(4*2*22) = -32 In order for the parabolas to make contact with each other the discriminant must equal zero or be above zero.
How much greater is 4 squared than 3 squared?
The greatness of 4 squared and 3 squared is expressed by the equation: 16 - 9 which equals 7.3 squared equals 3 x 3 = 94 squared equals 4 x 4 = 1616 - 9 = 7
What are the value of 4 squared?
4 squared is 4 x 4 which equals 16.
What is the answer to -x equals 4?
-(2)Squared = 4
How do you prove that the line y equals x-4 is tangent to the curve of x squared plus y squared equals 8?
equation 1: y = x-4 => y2 = x2-8x+16 when both sides are squared equation 2: x2+y2 = 8 Substitute equation 1 into equation 2: x2+x2-8x+16 = 8 => 2x2-8x+8 = 0 If the discriminant of the above quadratic equation is zero then this is proof that the line is tangent to the curve: The discriminant: b2-4ac = (-8)2-4*2*8 = 0 Therefore the discriminant is equal to zero thus proving that the line is tangent to the curve.
How do you find 9x squared plus four x plus 2 equals zero?
It has no solutions because the discriminant is less than zero.
What is the answer to x squared equals 16?
4
Using the discriminant how many times does the graph of this equation cross the x-axis 5x squared -10x-2 equals 0?
Discriminant = (-10)2 - 4*5*(-2) = 100 + 40 > 0 So the quadratic has two real roots ie it crosses the x-axis twice.
X squared plus y squared plus z if x equals 7 y equals 6 and z equals 4?
