Add these polynomials and simplify. enter your response in standers form (x^4-9+5x^7) + ( 5x -10 +3x^4 - 2x^2)

5x^7 + 4x^4 - 2x^2 + 5x - 19

Step-by-step explanation:

Start by copying 5x -10 +3x^4 - 2x^2 here.  Next, add x^4 to +3x^4, -9 to -10, and 5x^7:

5x - 10 +3x^4 - 2x^2

     -  9  +x^4               + 5x^7

5x - 19 + 4x^4 - 2x^2 + 5x^7

Now rearrange these terms in descending order by powers of x:

5x^7 + 4x^4 - 2x^2 + 5x - 19   (answer)

5x^7+4x^4-2x^2+5x-19

Step-by-step explanation:

(x^4-9+5x^7)+(5x-10+3x^4-2x^2)

x^4+3x^4+5x^7-2x^2+5x-9-10

5x^7+4x^4-2x^2+5x-19

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

your answer is the frist one
