Solve the equation 12x2 -7x+1=0 by fatorising the LHS(lefthandside)
Can someone help please?
12x2 -7x+1=0 → (4x - 1)(3x - 1)
Note that the constants must both be +1 or -1, and since the -7x term is negative they must both be -1. Also the factors of 12 must sum to 7. This means only 3 and 4 will do.
The solutions are therefore given by 4x -1 = 0 or x = 1/4 and 3x - 1 = 0 or x = 1/3
