Plz solve it quickly ​

Answer 1

Step-by-step explanation:

1. (3x+7)²=(3x-7)²+168
2. {(3x×3x)+(7×7)}={3x×3x)-(7×7)}+168
3. 9x²+49=9x²-49+168
4. 9x²-9x²=-49-49+168
5. 0²=-98+168
6. 0=70

• hence there will be no value for X
• please check it question
• if the question is right
• then my answer should also be correct

Answer 2
