Question

if 49 x power 4 minus y equal to 7 x + 1 by 2 into 7 x minus 1 by 2 then the value of Y is ​

Answer 1

Step-by-step explanation:

• According to the question
• 49x^4-y=7x+1/2*7x-1/2
• 49x^4-y=(7x)^2-(1)^2/4
• $x + y \times x - y = x {}^{2} - y {}^{2}$
• 49x^4-y=7x^2-1/4
• 49x^4-y/49x^2-1=1/4
• x^2-y=1/4
• x^2=1/4+y
• x^2-1/4=y
• 4x^2-1/4=y.........Ans

• Hope this will help you......
