(2a^2 – ab)(a+4b^2) write as a polynmial

(2a^2-ab)( a+4b^2)

=> 2a^2(a) + 2a^2( 4b^2) - ab(a) - ab( 4b^2)

=>2a^3 + 8 a^2b^2 - a^2b - 4ab^3

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.
