What does it mean if an equation equals 0 does it have one solution no solution or indefinitely many solutions?
It has infinitely many solutions.
What are the solutions to the quadratic equation n2 -n -90 equals 0?
If: n squared -n -90 = 0 Then the solutions are: n = 10 or n = -9
Write a quadratic equation with these numbers -7 and -4 as solutions?
-3
What are the solutions to the simultaneous equation of 3x plus 2y equals 5x plus 2y equals 14 showing work?
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
If a equals positive and b equals negative and c equals zero how many solutions does a Quadratic Equation have?
Two: one is 0, the other is -b/a ax2 + bx + c = 0, but c = 0 ⇒ ax2 + bx + 0 = 0 ⇒ ax2 + bx = 0 ⇒ x(ax + b) = 0 ⇒ x = 0 or (ax + b) = 0 ⇒ x = -b/a
How many solutions does 0 equals 0 have?
0 = 0 is an identity and not an equation. Equations have solutions, identities do not.
What does it mean if an equation equals 0 does it have one solution no solution or indefinitely many solutions?
It has infinitely many solutions.

Does this equation have two real solutions 7x2 -8x -6 equals 0?
yes
What are the solutions to the quadratic equation n2 -n -90 equals 0?
If: n squared -n -90 = 0 Then the solutions are: n = 10 or n = -9
What are solutions to the equation x2-3x-4 equals 0?
They are x = -1 and x = 4.
How many solutions will the equation 25 equals 2x squared-6x have?
2x2 - 6x - 25 = 0. Solutions are 5.34 and -2.34
How many real solutions are there for the equation x2 plus 3x plus 5 equals 0?
There are no real solutions because the discriminant of the quadratic equation is less than zero.
