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.
When will you apply surds in real life?
You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.
What is the name of a curved line equation in graphs?
The one that forms a parabola (a hump, sort of) is called the quadratic expression or quadratic formula.
What is the expression of x2 12x 35?

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.
What would identify an expression as quadratic?
An expression is quadratic is the equation is in the form ax2 + bx + c. a, b, and c are all constants. They may be different or equal.
The discriminant in the quadratic formula is the expression?

When will you apply surds in real life?
You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.
How did you find each product of quadratic equations?
You substitute the value of the variable into the quadratic equation and evaluate the expression.
Can all quadratic expressions be factorised?
Only when the discriminant of the quadratic expression is equal to or greater than zero
