Find the product: (2x –2)(x –1)a.2x2 + 4x -2b.2x2 + 4x + 2c.2x2 -4x + 2d.2x2+ 2

FOIL:

First:

2x^2

Outside:

-2x

Inside:

-2x

Last:

2

Put it together:

2x^2 -2x -2x +2

combine like terms:

2x^2 - 4x +2

because they could drop even lower..

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
