Question?

OpenStudy (anonymous):

Solve using the quadratic formula. Approximate answers to the nearest tenth.m^2+6m-9=0

OpenStudy (anonymous):

m² + 6m - 9 = 0 Solving for the roots of a quadratic equation gives :- m =[ -6 ± √(6² + 36)] ÷ 2 : which simplifies to -3 ± 3√2 = -3 ± 4.243 (3dp) m = -7.2 and m = 1.2 (Answers to the nearest tenth)

OpenStudy (anonymous):

so the answer is m=-7.2,1.2

OpenStudy (anonymous):

Sorry, yes the answer is m= -7.2,1.2.
