C.2.4—Solving algebraic equations

Solve algebraic equations, including quadratic equations and kinematic equations for constant acceleration.

Use c.2.4—solving algebraic equations to connect the rule to the data and decision in the question.

This matters because c.2.4—solving algebraic equations determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply c.2.4—solving algebraic equations to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.
