Question

5(x - 5) (x + 5) = 55.​

Answer 1

Answer:

$\sqrt{30}$

Step-by-step explanation:

= 5(x - 5) (x + 5) = 55

= $5 ( x^{2} -25)=25 [ (a+b)(a-b) =a^{2}-b^{2} ]$

= $( x^{2} -25)=\frac{25}{5}$

= $x^{2} -25=5$

= $x^{2} =5+25\\x^{2} =30\\x = \sqrt{30}$

Answer 2

ok that is the answer and look see it
