Answer

Use the quadratic equation formula:

x2 + 5x - 25 = 0

(x + 8.090169944).(x - 3.090169944) = 0

Therefore: x = - 8.090169944 or x = 3.090169944

Check that the answer is correct by multiplying out the brackets.

SolutionTo solve this equation, we will have to use the formula:
x1 = [-b + sqrt(b2 - 4ac)]/2a
x2 = [-b - sqrt(b2 - 4ac)]/2a

a = 1
b = 5
c = -25

We get the same answers as above.
