Question

factorise:-
√7x^2+9x+2√7

Answer 1

Here is your answer....

root 7 x^2 + 9x + 2 root 7 = 0

root 7 x^2 + 7x + 2x + 2 root 7 = 0

root 7 x(x + root 7) + 2( x + root 7) = 0

(x + root 7)(root 7 x + 2) = 0

Now,

x + root 7 = 0 or root 7 x + 2 = 0

x = -root 7 or x = -2/root 7

Hope this will help you.....

Answer 2

$\sqrt{7} x {}^{2} + 9x + 2 \sqrt{7}$

$\sqrt{7} \: {x}^{2} + 7x + 2x + 2 \sqrt{7}$

$\sqrt{7} \: x(x + \sqrt{7} ) + \: 2(x + \sqrt{7} )$

$( \sqrt{7} x \: + \: 2) \: (x + \sqrt{7)}$
