FACTORISE The Qudratic
Equation. y2-6y-7=0​

Factor y2−6y−7 using the AC method.

(y−7)(y+1)=0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

y−7=0

y+1 =0

Set y−7 equal to 0 and solve for y.

y=7

Set y+1 equal to 0 and solve for y.

y= −1

The final solution is all the values that make

(y−7)(y+1)=0 true.

y=7,−1

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
