Can you please put these polynomials in shorter form: )?

Question

a) 6x+7+3x

b)3x+5

c)4x+8xy-7

d)2x(x-10)

e)(2x+3)(x-5)

f)3x(x-4)+7x+8

Answer 1

a)

6x+7+3x =

x(6 + 3) + 7 =

9x + 7

b)3x+5  This is the simplest form.

c)

4x+8xy-7 =

x(4 + 8y) - 7 =

4x(1 + 2y) - 7

d)

2x(x-10) =

2x² - 20x

e)

(2x+3)(x-5) =

2x² - 10x + 3x - 15

2x² - 7x - 15

f)

3x(x-4)+7x+8 =

3x² - 12x + 7x + 8 =

3x² - 3x + 8

Hope this helps you!
