Question

Solve  equation using the quadratic formula.
   x^2+25=0. Please show me the steps.

anonymous · Answer

is this dealing with imaginary numbers?

anonymous · Answer

we havn't done with imaginary numbers

anonymous · Answer

ok

anonymous · Answer

x^2+25
(x+5)(x-5)=0
x=-5, x=5

anonymous · Answer

Is it difference between the squares

anonymous · Answer

Do u think we need not to use the quadratic formula

anonymous · Answer

Add 25 to both sides of the equation to get
x^2 = 25
Take the square root of both sides of the equation to get
x = ±√25 = ±5
x = 5 and x = -5 are solutions to this equation.

You can recognize that the difference of two squares is a standard form that you know the factors for. A2 - b2 = (a+b)(a-b)
x2 - 25 = (x+5)(x-5) = 0
Values of x that make the factors zero are
x = -5, x = 5 (same as above)
