1)


1.x^2+8x-6=0


D=8^2-4.1. (-6)


D=88


x1= -8+square root of 88/2.1


x2= -8- square root of 88/2.1


3)


x^2-10x-32=0


D=(-10)^2-4.1. (-32)=228


x1=10+square root of 288/2.1


x2=10- square root of 288/2.1


5)


x^2+4x+10=0


D=4^2-4.1.10= -24


x1=-4+2i.square root of6/2.1


x2= -4-2i.square root of 6/2.1
