Tolong dijawab k Soalnya mau ujian

[tex]lim \: \: \: \: \: \: \: \: \: \: \: \: \: ( \sqrt{a {x}^{2} + bx + c } - \sqrt{p {x}^{2} + qx + c } \\ x = > \infty \\ jika \: a = p \: maka \: hasil \: limit \: = \frac{b - q}{2a} \\ = ( \sqrt{4 {x}^{2} - 4x - 3 } - \sqrt{( {2x - 5)}^{2} } \\ = \sqrt{4 {x}^{2} - 4x - 3} - \sqrt{4 {x}^{2} - 20x + 25} \\ = \frac{ - 4 - ( - 20)}{2 \sqrt{4} } = \frac{16}{4} = 4[/tex]
