Answer:
x= -5 + 5
, x= -5 - 5
Step-by-step explanation:
Since this quadratic is set to zero, we can use the quadratic formula to solve this.
x^2 + 10x - 2400 = 0
Quadractic formula = x= -b +-
/2a
For this equation:
a= 1, b=10, c=-2400
Plug these numbers into the equation and solve.
x= -10 +-
)/2(1)
x= -10 +-
/2
x= -10 +-
/2
x= -10 +-
/2
x= -10 +- 5 * 2
/2
x= -10 +- 10
/ 2
Divide by 2.
x= -5 +- 5
Answer:
x= -5 + 5
