What are the soultion(s) to the quadratic equation 40- x^2=0

Step-by-step explanation:

40 - x^2 = 0...subtract 40

-x^2 = -40multiply both sides by -1

x^2 = 40

x = (+ - ) sqrt 40

x = (+ - ) sqrt 4 * 10

x = (+ - ) 2 sqrt 10

x = 2 sqrt 10, and x = -2 sqrt 10

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
