Answer 2

Answer:

step 1-x*x=$x^{2}$

now,

step 2-$x^{2}$+4=9

$x^{2}$=9-4=5

x=$\sqrt{ 5$

Step-by-step explanation:

in the first as they have said that x is multiplied by x so.. we did that in step 1 by multiplying it. then they have said that the result of the step 1 should be added to 4 to get 9.. as we have done it in step 2...and then solved it by bringing the +4 to the right side by (-)ing with 9 and thus we get our result and then the squaring of the x come this side and become$\sqrt{5}$.and thus this is the value of the x
