Question

-x²-x+6 va rog cat mai repede

Answer 1

-X²-X+6=0
a=-1
b=-1
c=6
∆=b²-4ac
∆=(-1)²-4×(-1)×6
∆=1+24
∆=25
X(1,2)=(-b±√∆)/2a
X(1,2)=(-(-1)±√25)/(2×(-1))
X(1,2)=(1±5)/-2
X(1)=(1+5)/-2
X(1)=6/-2
X(1)=-3
X(2)=(1-5)/-2
X(2)=-4/-2
X(2)=2

Answer 2

${-x ^{2} }-x+6$
${-x ^{2} }+2x-3x+6$
$-x\cdot(x-2)-3(x-2)$
$(-x-3)\cdot(x-2)$
