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.
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 do you write an expression in radical form?
Re-write it with a root. If the power of the expression is less than 1, for example x1/3, the expression could be rewritten as cube root of x.
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.
When the roots are equal of a quadratic equation?
Write the quadratic equation in the form ax2 + bx + c = 0 The roots are equal if and only if b2 - 4ac = 0. The expression, b2-4ac is called the [quadratic] discriminant.
