Question

find the value of 'a'and 'b'
answer is a= -4/3 and b= 11/3 please give correst answer​

Answer 1

$\frac{ \sqrt{7} - 2}{ \sqrt{7} + 2 } \times \frac{\sqrt{7} - 2}{\sqrt{7} - 2} = a \sqrt{7} + b$

$\frac{( \sqrt{7} - 2) {}^{2} }{( \sqrt{7}) {}^{2} - 2 {}^{2} } = a \sqrt{7} + b$

$\frac{7 + 4 - 4 \sqrt{7} }{7 - 4} = a \sqrt{7} + b$

$\frac{11 - 4 \sqrt{7} }{3} = a \sqrt{7} + b$

$\frac{ - 4 \sqrt{7} }{3} + \frac{11}{3} = a \sqrt{7} + b$

On comparison

$<strong> </strong><strong>a = – 4/3</strong>$

and

$<strong> </strong><strong>b = 11/</strong><strong>3</strong>$

Please mark me great if you understood the solution

Answer 2

answer is a=-4/3 and b=11/3
