Is this correct now.
Problem #1
solve by completing the square.
2x^2+8x+3=0
My answer: x=-2 +/- sqrt (5)/(2)
Problem #2
solve by using the quadratic formula
5x^2+3x+1=0
My answer: No solution are defined.
You are not completing the square.
2x^2+8x+3=0
x^2 + 4x =- 3/2 now complete the square..
x^2 + 4x + 4 =- 3/2 + 4
(x+2)^2= ( sqrt (2.5))^2
x+2 = +- sqrt 2.5
to your answer above now.
isn't this the same answer as what i have
