Question

sherly says that solutions of the quadratic equations w2=49 and w2 + 49= 0 are the same. do you agree with sherlyu? jutify your answer

Answer 1

Answer:

i dont agree with sherly

bcoz if w2=49 then w = 24.5

but of w2 + 49 = 0 then w2 = -49 then w = -24.5

therefore 24.5 is not equal to -24.5

hence i dont agree with sherly
