Answer 1

x²+6x=16
x²+6x-16=0
x²-8x+2x-16=0
x(x-8)+2(x-8)=0
(x-8)(x+2)=0
x=8
x=-2

x²-2x-8=0
x²-4x+2x-8=0
x(x-4)+2(x-4)=0
(x-4)(x+2)=0
x=4
x=-2

4x²-4x=8
4x²-4x-8=0
4(x²-x-2)=0
4(x-2)(x+1)=0
x=2
x=-1

4x²+12x=16
4x²+12x-16=0
4(x²+3x-4)=0
4(x-4)(x+1)
x=4

x²-8x+7=0
(x-7)(x-1)=0
x=7
x=1

x²+4x=12
x²+4x-12=0
(x-2)(x+6)
x=2
x=-6

x²-6x=7
x²-6x-7=0
(x-7)(x+1)=0
x=7
x=-1

x²-4x=32
x²-4x-32=0
(x-8)(x+4)=0
x=8
x=-4

x²-12x=28
x²-12x-28=0
(x-14)(x+2_=0
x=14
x=-2
