Solving $ax^2 + c = 0$
Master Solving $ax^2 + c = 0$ in Grade 9 Saxon Algebra 1. Property To solve an equation in the form , you must first isolate the term (Saxon Algebra 1, Grade 9)
Key Concepts
Property To solve an equation in the form $ax^2 + c = 0$, you must first isolate the $x^2$ term. Explanation It's a two step puzzle! Before using your square root superpower, get $x^2$ all by itself. Use inverse operations to clear out the numbers tagging along with the variable. Examples $3x^2 75 = 0 \implies 3x^2 = 75 \implies x^2 = 25 \implies x = \pm 5$ $x^2 + 9 = 58 \implies x^2 = 49 \implies x = \pm 7$.
