Question

What is the difference of ( 3x^2 - 2x +5 ) - ( x^2 + 4x - 11 ) written in standard form ?

Answer 1

Negative six plus 2x by (x plus 1)

Explanation:

(3x^2 - 2x + 5) - (x^2 + 4x - 11)

(3x^2 - 2x + 5) - (x^2 + 4x - 11)

3x^2 - 2x + 5 - x^2 + 4x - 11

2x^2 + 2x - 6

= -6 + 2x (x + 1)

Answer 2

–3x + 22

Explanation:

x + 2(x – [3x – 8] + 3)

x + 2(x – 1[3x – 8] + 3)

x + 2(x – 1[3x] – 1[–8] + 3)

x + 2(x – 3x + 8 + 3)

x + 2(–2x + 11)

x + 2(–2x) + 2(+11)

x – 4x + 22

1x – 4x + 22

–3x + 22
