Question

Solve this equation x^2-60x-2700=0
BY QUADRATIC FORMULA.​

Answer 1

Answer:

$x = \frac{ - b + \sqrt{ {b}^{2} - 4ac } }{2a}$

and

$x = \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a}$

are two roots of the quadratic equation

$a {x}^{2} + bx + c = 0$

Comparing with this equation x^2-60x-2700 , we get

a=1, b= -60 and c =2700.

x = 60+120/2 and x =60-120/2 So the solutions to the above equation is -30 and 90. Hope it helps you. Mark me as Brainliest.

Answer 2

Answer:

x=90,-30

Step-by-step explanation:

x²-60x-2700=0

x=(60+ - √3600-4×-2700×1)/2×1

x=(60+ - √3600+10800/2

x=(60+ - √14400)/2

x=(60+ - 120)/2

x=30+ - 60

so x=30+60=90

and x=30-60=-30
