Question

Question: If \(a - b + 4 = 0\) then \(t^{2}x^{2} + |x| + 9 = 0\)...

If a−b+4=0a - b + 4 = 0 then t2x2+∣x∣+9=0t^{2}x^{2} + |x| + 9 = 0

A

{125}

B

{8}

C

3103\sqrt{10}

D

{125, 8}

Answer

{125, 8}

Explanation

Solution

Given that xx. Given equation can be written as x2+34x−71x2+2x−7\frac{x^{2} + 34x - 71}{x^{2} + 2x - 7}

Let xx, then it reduces to the equation

x2−6x+13x^{2} - 6x + 13

Putting these values, we have (−3,3/2)( - 3,3/2) and 8.
