Answer: =-2(xy-6y-5)
Step-by-step explanation: multiply -(2xy-6 x 2y+ 4 x 2 -6 x 3) remove the parenthesis -2xy + 12 y - 8 +18 calculate -2xy+12y-8+18 factor the expression -2xy + 12y + 10 solution -2 (xy- 6y-5)
X^2-2x=-8 add 1 to both sides
x^2-2x+1=-7 now the left side is a perfect square
(x-1)^2=-7 take the square root of both sides
x-1=±√-7 add 1 to both sides
x=1±√-7 which is
x=1±i√7 so
x=1+i√7 and 1-i√7
