(3x+1)(4x-1)

3x+4x=7x
1-1=0

So

(3x+1)(4x-1) = 7x

The midpoint of ABis M (0,-7). If the coordinates of A are (-2,-6), what are the coordinates of B?
DENIUS [597]

The coordinates of B will be "(2, -8)".

Given:

Midpoint of AB,

(x, y) = (0, -7)

Coordinates of A,

(x₁, y₁) = (-2, -6)

As we know,

The formula of midpoint is:

→ X =\frac{x_1+x_2}{2}

    0=\frac{-2+x_2}{2}

    0=-2+x_2

  x_2=2

→ Y=\frac{y_1+y_2}{2}

 -7=\frac{-6+y_2}{2}

-14=-6+y_2

   y_2=-14+6

   y_2=-8

hence,

→ (x_2,y_2)=(2, -8)

Thus the above answer is correct.
