Solve by completing the square:
x^2+3x-9=0

A.) x=3√5/4 +3/2 or -3√5/4+3/2
B.) x=3√5/2 -3/2 or -3√5 /2 +3/2
C.) x=3√5 /2 -3/2 or -3√5/2 - 3/2
D.) x= 3 √ 5/4 -3/2 or -3√5 /4 -3/2

i wish i could you, i have no idea how to answer this

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
