Detailed Solution

The given linear equation is

8 x 2 − 22 x − 21 = 0

.
We can solve the above equation using the factorization method.

8 x 2 − 22 x − 21 = 0 8 x 2 − 28 x + 6 x − 21 = 0 4 x (2 x − 7) + 3 (2 x − 7) = 0 (2 x − 7) (4 x + 3) = 0

Thus, the values are

x = 72

and

x = − 34

.
So, the given statement is false.
The correct statement is- If

, then
