Question

middle term splitting of 5 x square + 90 X + 1800​

Answer 1

$5 {x}^{2} + 90x + 1800$

splitting the middle term is not possible since discriminant is smaller than zero

Answer 2

Answer:

5x^2 + 90x + 1800

= 5( x^2 +18x + 360)

=5((x+9)^2. +360 -81)

= 5((x+9)^2 +279)

not possible contains complex roots
