What is the difference between quadratic equation and quadratic expression?
an equation has an equals sign.
How do you check whether the equation 7x2x is quadratic?
If it doesn't have an equal sign, then it's an expression, not an equation. The expression 7x2x is quadratic, because it equals 14x², and something is quadratic if it contains the squared exponent ².
Can all quadratic expressions be factorised?
Only when the discriminant of the quadratic expression is equal to or greater than zero
How did you find each product of quadratic equations?
You substitute the value of the variable into the quadratic equation and evaluate the expression.
How do you know whether it is possible to factorise a quadratic expression?
Look in an advanced maths book.Improved answer:-If the discriminant of the quadratic expression is less than zero then it's not possible to factor it.
What is the quadratic equation used for?
It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.
Is quadratic sequence exponential function?
No. It is a sequence for which the rule is a quadratic expression.
X 10 a quadratic expression?
No
What is the difference between quadratic equation and quadratic expression?
an equation has an equals sign.
What is a quadratic expression?
A quadratic expression is an expression which is written in the form ax2+bx+c, where a, b, and c represent constants, x represents a variable, and a is not equal to 0.
What is an example of a quadratic expression?
x2 + 3x + 4 This is quadratic because the highest exponent of x is 2, and it is an expression because there is no equals sign.
How do you check whether the equation 7x2x is quadratic?
If it doesn't have an equal sign, then it's an expression, not an equation. The expression 7x2x is quadratic, because it equals 14x², and something is quadratic if it contains the squared exponent ².
The discriminant in the quadratic formula is the expression?
b2-4ac
Is 3x²-4 a quadratic?
7
When will you apply surds in real life?
You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.
Can all quadratic expressions be factorised?
Only when the discriminant of the quadratic expression is equal to or greater than zero
How did you find each product of quadratic equations?
