Chapter Summary
Understanding the definition of a polynomial, its degree, and classifying polynomials as linear, quadratic, or cubic based on their degree. This includes recognizing their standard forms.
Calculating the value of a polynomial for a given real number and understanding that a 'zero' of a polynomial p(x) is a number 'k' such that p(k) = 0.
Understanding that the zeroes of a polynomial are the x-coordinates of the points where its graph intersects the x-axis.
Determining the number of zeroes of a polynomial by observing its graph. This includes analyzing linear graphs (straight lines), quadratic graphs (parabolas), and cubic curves.
For a quadratic polynomial ax² + bx + c, understanding and applying the relationships for the sum of zeroes (α + β = -b/a) and the product of zeroes (αβ = c/a).
Constructing a quadratic polynomial when the sum and product of its zeroes are given, typically using the form k[x² – (sum of zeroes)x + (product of zeroes)].
Applying the division algorithm to divide one polynomial by another and expressing the result in the form Dividend = Divisor × Quotient + Remainder, or p(x) = g(x)q(x) + r(x).
