Solve Rational Equations Using Their LCD - dummies
WebWith rational equations we must first note the domain, which is all real numbers except . (Recall, the denominator cannot equal zero. Thus, to find the domain set each denominator equal to zero and solve for what the variable cannot be.) The least common denominator or and is . Multiply every term by the LCD to cancel out the denominators. WebBy Formula Method. Solving an equation of quadratic type using the formula. x = [-b ± √ [ (b 2 -4ac)]/2a helps us find the roots of the quadratic equation ax 2 + bx + c = 0. Plugging in the values of a, b, and c in the formula, we arrive at the solution. Consider the example: 9x 2 -12 x + 4 = 0. a= 9, b = -12 and c = 4. can bad posture cause anxiety
