Solve the equation by completing the square. round to the nearest hundredth if necessary. x2 + 3x = 25

we are given

We can complete square

we can write it as

now, we can add both sides (3/2)^2

now, we can use formula

we can write it as

now, we can take sqrt both sides

we will get as

first solution:

Second solution:

so, solutions are
