Question Solve the inequality Solve the inequality by testing the values in the interval Solve for x x∈∅Alternative Form No solution Evaluate −x2−3x−4>0Rewrite the expression −x2−3x−4=0Add or subtract both sides −x2−3x=4Divide both sides −1−x2−3x=−14Evaluate x2+3x=−4Add the same value to both sides x2+3x+49=−4+49Simplify the expression (x+23)2=−47Since the left-hand side is always positive or 0,and the right-hand side is always negative,the statement is false for any value of x x∈/RThere are no key numbers,so choose any value to test,for example x=0 x=0Solution More Steps Evaluate −02−3×0−4>0Any expression multiplied by 0 equals 0 −02−0−4>0Simplify More Steps Evaluate −02−0−4Calculate −0−0−4Removing 0 doesn't change the value,so remove it from the expression −4 −4>0Check the inequality false x∈∅Alternative Form No solution Show Solution
