MAT-09.AR.10

BPSS-MAT-NO logo 9th Grade (MAT) Targeted Standard  
  (AR) Algebraic Reasoning 
Learners will look for, generate, and make sense of patterns, relationships, and algebraic symbols to represent mathematical models while adopting approaches and solutions in novel situations.
MAT-09.AR.10 Solve quadratic equations in one variable by inspection (e.g., for x² = 49) taking square roots, the quadratic formula, and factoring, as appropriate to the initial form of the equation.

Quadratic Equations
  • MAT-09.AR.10 Solve quadratic equations in one variable by inspection (e.g., for x2 = 49) taking square roots, the quadratic formula, and factoring, as appropriate to the initial form of the equation.
  • MAT-12.NO.09 Apply the Fundamental Theorem of Algebra to determine the number of zeros for polynomial functions. Find all solutions to a polynomial equation.
  • MAT-12.AR.07 Create equations and inequalities and use them to solve problems. Include equations arising from linear and quadratic functions and simple rational and exponential functions.
  • MAT-12.AR.10 Derive the quadratic formula from the form 0 = ax2 + bx + c.
  • MAT-12.AR.11 Solve quadratic equations with real coefficients that have solutions of the form a + bi and a - bi.
  • MAT-12.AR.14 Identify zeros of polynomials when suitable factorizations are available. Use the zeros to construct a rough graph of the function defined by the polynomial.
  • MAT-12.AR.17 Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically.
