Standards

Common Core

• HSA.APR.D.7 – Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.

• HSA.SSE.B.3.A – Factor a quadratic expression to reveal the zeros of the function it defines.

• HSF.IF.C.7.A – Graph linear and quadratic functions and show intercepts, maxima, and minima.

TEKS

• A.7(A) – graph quadratic functions on the coordinate plane and use the graph to identify key attributes, if possible, including x-intercept, y-intercept, zeros, maximum value, minimum values, vertex, and the equation of the axis of symmetry

• A.10(B) – multiply polynomials of degree one and degree two

• A.10(E) – factor, if possible, trinomials with real factors in the form ax² + bx + c, including perfect square trinomials of degree two
