Question

SOLVE BY COMPLETING THE SQUARE : X^2+6X+3=19

Answer 1

x^2+6x+3=19


x^2+6x=19-3


x^2+6x=16


x^2+6x+9=16+9


(x+3)^2=25


x+3 = +-sqrt(25)


x+3 = sqrt(25) or x+3 = -sqrt(25)


x+3 = 5 or x+3 = -5


x = 5-3 or x = -5 - 3


x = 2 or x = -8

Answer 2

X^2+6X+3=19 ===> X^2+6X+9 =19+3+9 ===> (x+3)^2=31
