Question

3 into 2 - 5 x minus 2 into 1 minus 6 x is equal to 1​

Answer 1

Answer:

3(2-5x)(1-6x)=1

(2-5x)(1-6x)=1/3

On opening the bracket,

2-17x+30x^2=1/3

On bringing 3 to the other side

=6-51x+90x^2

or

90x^-51x+6

Solving the quadratic equation,

=90x^2 - 36x - 15x +6

=18x(5x - 2) -3(5x - 2)

18x - 3=0          x=3/18

=1/6

or

5x - 2=0           x=2/5

=2/5
