what is the solution for x^2-4x=?

Step-by-step explanation:

Compare the powers

x² + 4x + 4 = 9x + 18

x² + 4x + 4 - 9x -18 = 0

x² -5x -14 = 0

x² -7x + 2x - 2 *7 = 0

x(x-7) + 2(x - 7) = 0

(x-7)(x+2) = 0

x - 7 = 0    or x + 2 = 0

x = 7         or x = -2

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)
