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

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

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
