Remark

When two chords intersect, the segments of one line multiplied together equal the second line's segments multiplied together.

Givens

3x*(x+ 1) = k

4x * x = k

Substitute and solve.

3x*(x + 1) = 4x * x Remove the brackets.

3x^2 + 3x = 4x^2 Bring the left side over to the right side.

0 = 4x^2 - 3x^2 - 3x

0 = x(x - 3)

One of the answers is 0

the other value of x = 3. O would have no meaning.
