Can quadratic systems be solved using elimination and substitution?
HotAnswerer
You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.

The ELIMINATION method performs operations on a system of equations to?
Simultaneous equations can be solved using the elimination method.
How an algebric expression with quadratic denominator is solved?
Algebraic expressions can't be solved because they are not equations but they can be simplified.
What does it mean in algebra to complete the square?
A quadratic equation can be solved by completing the square which gives more information about the properties of the parabola than with the quadratic equation formula.
Can anyone help with this problem solve Quadratic problem 3x2 4X -2 0?
If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla
Use addition or substitution to find the value of x for this set of equations for x - y equals 120 x plus y equals 150?
X = 135 and y = 15 Solved by addition and substitution
What can systems of equations be solved by?
By elimination or substitution
IF you need to solve large systems with more than three variables which method is more efficient and why?
For systems with more than three equations, Gaussian elimination is far more efficient. By using Gaussian elimination we bring the augmented matrix into row-echelon form without continuing all the way to the reduced row-echelon form. When this is done, the corresponding system can be solved by the back-substitution technique.
What part of the a quadratic formula tells you when the quadratic equation can be solved by factoring?
The discriminant
What is the quadratic formula for?
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
What is equadtratic equation?
A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.
The ELIMINATION method performs operations on a system of equations to?
Simultaneous equations can be solved using the elimination method.
How an algebric expression with quadratic denominator is solved?
Algebraic expressions can't be solved because they are not equations but they can be simplified.
Which method would be best for solving the system x 8y plus 5 and 3x - 2y 11?
If you mean: x = 8y+5 and 3x-2y = 11 then the simultaneous equations can be solved by a process of elimination. -------------------- Since the first equation is solved for x, substitution should be easy. There is no "right" answer to this question - it depends on your taste and experience.
What does quadratic formula find?
When an equation cannot be solved for "x" to find the zeroes, the quadratic formula can be used instead for the same purpose.
Can Quadratic equations that can be solved using the quadratic formula also be solved by factoring?
Yes, however not all quadratic equations can easily be solved by factoring, sometimes you can factor and sometimes it is easier to use the quadratic formula. Example: x2 + 4x + 4 This can be easily factored to (x + 2)(x +2) Therefore the answer is -2 by setting x +2 = 0 and solving for x This can be done using the quadratic equation and you would get the same results, however, it was much faster to factor instead.
What is the answer of 4x2plus9equal12x?
It is a quadratic equation and when solved it has equal roots of 3/2 or 1.5
Who found the quadratic formula?
It comes from completing the square of a general quadratic. Many people believe Brahmagupta first solved this in 628 AD.
