Question

(7) X(X + 1)(x - 2)
"
(x+5)​

Answer 1

7×(x+1)(x‐2)=0

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0=7x² -7x-14=0

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0=7x² -7x-14=0=7x² -14x+7x-14=0

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0=7x² -7x-14=0=7x² -14x+7x-14=0=7x(x-2)+7(x-2)=0

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0=7x² -7x-14=0=7x² -14x+7x-14=0=7x(x-2)+7(x-2)=0=(7x+7)(x-2)

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0=7x² -7x-14=0=7x² -14x+7x-14=0=7x(x-2)+7(x-2)=0=(7x+7)(x-2)=(x+1)(x-2)

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0=7x² -7x-14=0=7x² -14x+7x-14=0=7x(x-2)+7(x-2)=0=(7x+7)(x-2)=(x+1)(x-2)=x=-1 & x=2

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0=7x² -7x-14=0=7x² -14x+7x-14=0=7x(x-2)+7(x-2)=0=(7x+7)(x-2)=(x+1)(x-2)=x=-1 & x=2

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0=7x² -7x-14=0=7x² -14x+7x-14=0=7x(x-2)+7(x-2)=0=(7x+7)(x-2)=(x+1)(x-2)=x=-1 & x=2 (x+5)=(-1+5) & (x+5)=(2+5)

7×(x+1)(x‐2)=0=7(x²+x–2x-2)=0=7x² -7x-14=0=7x² -14x+7x-14=0=7x(x-2)+7(x-2)=0=(7x+7)(x-2)=(x+1)(x-2)=x=-1 & x=2 (x+5)=(-1+5) & (x+5)=(2+5) =4. & =7
