Reduce to the form x + yi : 2 logsinh (-i+2) 40ežmi

If possible, write -6- 19x - 11x² as a linear combination of -1 - x - x², 1+ 2x + x² and -1 -3x - 2x². Otherwise, enter DNE in all answer blanks. (-1- x - x²)+ (1 + 2x + x²)+ -619x11x² = (-1-3x - 2x²).

Rewrite the following in the form y=a(x-h)^2+k   Y=x^2+7x+10

If possible, write -1- 12x - 8x² as a linear combination of -x-x², 2x + x² and 2x1 + x². Otherwise, enter DNE in all answer blanks. (-x-x²)+ -1-12x8x² (2x − 1 + x²). = (2x + x²)+
