Answer 1

Question?

Answer 2

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

Answer 3

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)

Answer 4

so the answer is m=-7.2,1.2

Answer 5

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