Answer:

option A is correct

Step-by-step explanation:

We simplify the given options

(a) (x^2-5x+13)+(x^2+3x-6)


combine like terms

[tex]x^2-5x+13+x^2+3x-6[/tex]

[tex]2x^2-2x+7[/tex]

(b)(4X^2-6X+11)+(2X^2-4X+4)

combine like terms

[tex]4x^2-6x+11+2x^2-4x+4[/tex]

[tex]6x^2-10x+14[/tex]

(c) (5X^2-8X+120)+(-3X^2+10X-13)

combine like terms

[tex]5x^2-8x+120-3x^2+10x-13[/tex]

[tex]2x^2+2x+107[/tex]
