Answer:
quadratic formula
Explanation:
Given the expression,
g ^2+ 18g+ 50 = 0?
To get the value of g we will have to use the quadratic formula as shown;
g = -b±√b²-4ac/2a
From the equation
a = 1, b = 18 and c = 50
g = -18±√18²-4(50)/2
g = -18±√324-200/2
g = -18±√124/2
g = -18+11.14/2 and -18-11.14/2
g = -6.86/2 and -29.14/2
g = -3.43 and -21.43
hence the correct option is quadratic formula
