Question

5x^2-5x+1 plus 2x^2+9-6

Answer 1

Hi there!

( 5x² - 5x + 1 ) + ( 2x² + 9 - 6 )

⇒ 5x² - 5x + 1 + 2x² + 9 - 6

⇒ 5x² + 2x² - 5x + 1 + 9 - 6

⇒ 7x² - 5x + 10 - 6

⇒ 7x² - 5x + 4

~ Hope it helps!

Answer 2

Hi there!

$(5 {x}^{2} - 5x + 1) + (2 {x}^{2} + 9 - 6)$
First we can subtract between the right parenthesis.

$(5 {x}^{2} - 5x + 1) + (2 {x}^{2} + 3)$
Now we can just remove the parenthesis, since they don't have a function in this situation.

$5 {x}^{2} - 5x + 1 + 2 {x}^{2} + 3$
Next up is rearranging the expression in order to collect the terms later.

$5 {x}^{2} + 2 {x}^{2} - 5x + 1 + 3$
And finally we can collect the terms.

$7 {x}^{2} - 5x + 4$
