Question

What is the result when the sun 4x^2+8x-1 and 7x^2-3x+8 is multiplied by 5x^2?

Answer 1

Answer:

55x^4+25x^3+35x^2

Step-by-step explanation:

5x²(4x^2+8x-1 and 7x^2-3x+8)

Applying distribution property,we have

• 5x^2(4x^2+8x-1 + 7x^2-3x+8)
• (5x^2)*(4x^2)+(5x^2)*(8x)+(5x^2)*(-1)+(5x^2)(7x^2)+(5x^2)*(-3x)+(5x^2)*(8)

Simplifying them,we have

• 20x^4+40x^3−5x^2+35x4−15x^3+40x^2
• 55x^4+25x^3+35x^2
