Question

-5x⁶+3x⁴+-4x³
9x⁶+4x⁴+20x³
____________ =?​

Answer 1

Answer:

Addition

(-5x⁶ + 3x⁴ + 20x³) + (9x⁶ + 4x⁴ + 20x³)

= -5x⁶ + 3x⁴ + 20x³ + 9x⁶ + 4x⁴ + 20x³

= -5x⁶ + 9x⁶ + 3x⁴ + 4x⁴ + 20x³ + 20x³

= 4x⁶ + 7x⁴ + 40x³

Subtraction

(-5x⁶ + 3x⁴ + 20x³) - (9x⁶ + 4x⁴ + 20x³)

= -5x⁶ + 3x⁴ + 20x³ - 9x⁶ - 4x⁴ - 20x³

= -5x⁶ - 9x⁶ + 3x⁴ - 4x⁴ + 20x³ - 20x³

= -14x⁶ - 1x⁴

Answer 2

Answer:

Step 1 =

Equation at the end of step 1

(((((0-(5•(×6)))+(3•(×3)))+(9•(×6)))+(4•(×4)))+(22•5×3)

Step 2 =

Equation at the end of step 2

(((((0-(5•(×6)))+(3•(×4)))-(4•(×3)))+(9•(×6)))+22×4)+(22•5×3)

Step 3 =

Equation at the end of step 3

(((((0-(5•(×6)))+(3•(×4)))-(4•(×3)))+32×6)+22×4)+(22•5×3)

Step 4 =

Equation at the end of step 4

(((((0-(5•(×6)))+(3•(×4)))-22×3)+32×6)+22×4)+(22•5×3)

Step 5 =

Equation at the end of step 5

(((((0-(5•(×6)))+3×4)-22×3)+32×6)+22×4)+(22•5×3)

Step 6 =

Equation at the end of step 6

(((((0-5×6)+3×4)-22×3)+42×6)+22×4)+(23•5×3)

Step 7 =
