Question

Add the following 9x^2-4x+5, -3x^2+5x-3, 4-3x​

Answer 1

Answer:

STEP1:

9 Simplify — 5

Equation at the end of step1:

9 ((((15•(x3))+(4•(x2)))-19x)+(—•x))-2 5

STEP 2 :

Equation at the end of step2:

9x ((((15•(x3))+22x2)-19x)+——)-2 5

STEP 3 :

Equation at the end of step3:

9x ((((3•5x3) + 22x2) - 19x) + ——) - 2 5

STEP4:Rewriting the whole as an Equivalent Fraction

 4.1   Adding a fraction to a whole 

Rewrite the whole as a fraction using  5 as the denominator :

15x3 + 4x2 - 19x (15x3 + 4x2 - 19x) • 5 15x3 + 4x2 - 19x = ———————————————— = —————————————————————— 1 5

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole 

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

STEP5:Pulling out like terms

 5.1     Pull out like factors :

   15x3 + 4x2 - 19x  =   x • (15x2 + 4x - 19) 

I hope u help.

pls comment and thanks

Answer 2

Answer:

6x^2 - 2x + 7

Step-by-step explanation:

solution....

(9x^2-4x+5) + (-3x^2+5x-3) + (4-3x)

= 9x^2-3x^2 +5x -4x - 3x + 5 - 3 +4

= 6x^2 +5x- 7x +9 - 3

=6x^2 - 2x + 7

hope it will help...
