Solutions are denoted by index. Most of the equations you listed has 2 solutions.

Number one cannot be factored using whole numbers.

Number two.

$4x^2+25=0\Longrightarrow(2x+5)(2x-5)=0 \\x_1\Longleftrightarrow\boxed{2x+5=0\Longrightarrow x=-\dfrac{5}{2}} \\ x_2\Longleftrightarrow\boxed{2x-5=0\Longrightarrow x=\dfrac{5}{2}}$

Number three.

$x^2+121=0\Longrightarrow(x+11)(x-11)=0 \\x_1\Longleftrightarrow\boxed{x+11=0\Longrightarrow x=-11} \\x_2\Longleftrightarrow\boxed{x-11=0\Longrightarrow x=11}$

Hope this helps.
