What are the solutions to -x squared plus 2x plus 4 and x-2?
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
What are the solutions to the simultaneous equations of x squared plus y squared equals 20 and 2y minus x equals 0?
The solutions are: x = 4, y = 2 and x = -4, y = -2
What are the solutions to the simultaneous equations of 2x plus y equals 5 and x squared -y squared equals 3?
If: 2x+y = 5 and x2-y2 = 3 Then the solutions work out as: (2, 1) and ( 14/3, -13/3)
What are the solutions to the simultaneous equations of x -2y equals 1 and 3xy -y squared equals 8?
They are: (3, 1) and (-11/5, -8/5)
Why is 6 squared rational?
Because 6 squared equals 36 and 36 terminates, or ends, which makes it rational.
What are the solutions of the simultaneous equations of x squared -xy -y squared equals -11 and 2x plus y equals 1?
1st equation: x^2 -xy -y squared = -11 2nd equation: 2x+y = 1 Combining the the two equations together gives: -x^2 +3x +10 = 0 Solving the above quadratic equation: x = 5 or x = -2 Solutions by substitution: (5, -9) and (-2, 5)
True or false the solution of the equation of x squared plus 4x equals 0 is identical to the solution of 3x squared plus 12x equals 0?
True. Both equations can be factored to x(x+4)=0 and 3x(x+4)=0, respectively. Therefore, the solutions for both equations are x=0 and x=-4. So, yes, the solutions are identical because math doesn't play favorites.
What are the solutions to the equations 3x -5y equals 16 and xy equals 7?
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
What are the solutions to the equations 7x-4y equals 13 and 2x-5y equals -4?
It works out that the solutions are: x = 3 and y = 2
How many solutions does 0 equals 0 have?
0 = 0 is an identity and not an equation. Equations have solutions, identities do not.
How many solutions will the equation 25 equals 2x squared 6x have?
The quadratic equation will have two solutions.
What are the values called at which the equation equals zero?
They are called the solutions or roots of the equations.
