2x²-7x+3=0 find x by completing the square​

Answer»

Step-by-step explanation:

divide both sides by 2

x^2 -7/2=-3/2

thrid term=(1/2*-7/2)^2

(-7/2)^2 = 49/16

add it to both sides

x^2-7/2x+49/16=-3/2+49/16

x^2-7/2+(7/4)^2=-24+49/16

(x-7/2)^2=25/16

taking SQUARE root

x-7/2=+-5/4

x=19/4 or x=9/4
