Aliya and Maya solved a quadratic equation. In solving it, Aliya made a mistake in the constant term and got the roots as 6 and 2, while Maya made a mistake in the coefficient of x only and obtained the roots as -7 and -1. What are the correct root of the equation ?
(x-6)(x-2)=x^2-8x+12 =0 --> +12 is wrong (x+7)(x+1)=x^2+8x+7=0 --> +8 is wrong so the correct one is: x^2-8x+7= 0 --> (x-7)(x-1)=0 ==> x= +7 and +1
Solve the following mathematical equation -
1 1 1 = 6 2 2 2 = 6 3 3 3 = 6 4 4 4 = 6 5 5 5 = 6 6 6 6 = 6 7 7 7 = 6 8 8 8 = 6 9 9 9 = 6
Use any instrument like + × ÷ - square root etc
