Question

Should I use factoring, square root property, completing the square, or the quadratic formula to solve these?

Answer 1

I can only use each once. I don't have to solve, just tell why I would use the particular method.

Answer 2

I picked factoring for C and said because each of the numbers are common factors of 4.

Answer 3

A. 4x^2 -27 = 0 add to both sides 27 and will get

4x^2 = 27 divide both sides by 4 and will get

x^2 = 27/4 mqke square root from both sides and get

x_1,2 = +/- sqrt(27/4) = +/- sqrt((9*3)/4) = +/- (3/2)sqrt3

hope helped

Answer 4

Do you know what B and D would be? @jhonyy9
