Question

help e to solve this
x^2 + 3x - 54

Answer 1

Given, x² + 3x - 54 = 0

--> x² + 9x - 6x - 54 = 0

--> x(x + 9) - 6(x + 9) = 0

--> (x - 6)(x + 9) = 0

x = 6 , x= -9

So, X = 6

Answer 2

Step-by-step explanation:

By Quadratic formula,

x= -3±√3^2-4*1(-54)/2*1

x=-3±15/2

One with a Add and the other with a Substract-

x=-3+15/2=6

x=-3-15/2=-9

Valves of x is:-

x=6 &

x=-9
