Solve the quadratic equation 2x to the 2nd power 3x2=0using the quadratic formula. Read the information in the assignment list to learn more about how to type math symbols in MS Word, such as the square root.

2 x^2  3 x  2 = 0
x = [ 3 +/ sqrt (9 + 16) ]/ 4
x = [ 3 +/ sqrt(25) ]/ 4
= [3+5]/4
or
= [35]/4
= 2 or 1/2
check:

(x2)(2x + 1) = 2 x^2 3x  2 yes
