Answer 2

Answer:

the answer is :

-16 -3x +1

Step-by-step explanation:

• 2x2 -5x +4 = 4 -5x+4
• -7x2 -8x +6 = -14 -8x+6

Now adding these numbers :

4 -5x +4

+ -14 -8x +6

-----------------------

-10 -13x +10

-----------------------

So by adding we get :

-10 -13x +10 ....equation 1

Now subtract 3x2 -10x +9 from equation1

• 3x2 -10x +9 = 6 -10x +9

=> -10 -13x +10

6 -10x +9

+ + - (sign will be changed in substrat)

------------------------

-16 -3x +1
