Factor and solve -1x^2 + 13x - 42 = 0

-1x^2 + 13x - 42 = 0

-1(x^2-13x+42)=0

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

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

Solve:

-1(x-7) =0

-1(x) (-1)(-7) =0

-1x+7=0

-1x+7-7=0-7

-1x=-7

-1x/-1=-7/-1

x=7

Solve:

-1(x-6) = 0

-1(x) (-1)(-6) = 0

-1x+6=0

-1x+6-6=0-6

-1x=-6

-1x/-1=-6/-1

x=6
