Question

find the root of the equation x^2+5x-1800​

Answer 1

sum of roots =-b by a

product of roots= c by a

Answer 2

Answer:

x = 40, x = -45

Step-by-step explanation:

Given equation,

$x^2 + 5x - 1800$

For finding roots,

$x^2 + 5x - 1800=0$

By middle term splitting,

$x^2 + 45x - 40x - 1800 = 0$

$x(x+45) - 40(x + 45) = 0$

$(x-40)(x+45) = 0$

By zero product property,

x - 40 = 0 or x + 45 = 0

⇒ x = 40 or x = -45
