The discriminant is 1-4*2*(-1) = 1+8 = 9.
This is greater than 0 so there are 2 real solutions.
2.
As many solutions as there are points in the domain.
Is a trigonometric equation which has infinitely many real solutions.
There are none. For this equation, there is nonreal answer, as the graph of the quadratic does not pass below the x-axis
One solution: x = -4
2.
The quadratic equation will have two solutions.
Infinitely many
Since the highest power of 'x' in the equation is '1', there's one solution.
As many solutions as there are points in the domain.
It has infinitely many solutions.
0 = 0 is an identity and not an equation. Equations have solutions, identities do not.
How many solutions are there to the equation below? 3x-10(x+2) = 13-7x 0
Is a trigonometric equation which has infinitely many real solutions.
There are none. For this equation, there is nonreal answer, as the graph of the quadratic does not pass below the x-axis
1
The equation has infinitely many solutions.
