a. -30x^7y^2 b. -30x^12y^3 c. -30x^12/y^3 d. -30x^7/y^2
solve the following equation.
8+x/2 - x+3/3=4
a. x=-14 b. x=6 c. x=14 d. x=-6
solve the equation.
x^2-3x-8=x+4
a. x=-6 or x=2 b. x=1+ sqrt5 or x=1- sqrt5 c. x=1+2sqrt3 or x=1-2sqrt3 d. x=-2 or x=6
joseph is solving the equation x^2+8x-4=0 using the technique completing the square. x^2+8x-4=0 x^2+8x+? =4+? what number should joseph add to both sides of the equation to complete the square, and why?
a. he should add 4 to both sides because 8/2=4. b. he should add 4 to both sides because (4/2)^2=4. c. he should add 16 to both sides because 16/2=8. d. he should add 16 to both sides because (8/2)^2=16.
