Simplify 8x^2-7x+2+(3x^2-9x-6)

simplify

8 x^{2} - 7 x + 2 + (3 x^{2} - 9 x - 6)

11 x^{2} - 16 x - 4

Solution steps

8 x^{2} - 7 x + 2 + (3 x^{2} - 9 x - 6)

Apply rule:

a + (b + c) = a + b + c

2 + (3 x^{2} - 9 x - 6) = 2 + 3 x^{2} - 9 x - 6

= 8 x^{2} - 7 x + 2 + 3 x^{2} - 9 x - 6

Group like terms

= 8 x^{2} + 3 x^{2} - 7 x - 9 x + 2 - 6

Add similar elements:

8 x^{2} + 3 x^{2} = 11 x^{2}

= 11 x^{2} - 7 x - 9 x + 2 - 6

Add similar elements:

- 7 x - 9 x = - 16 x

= 11 x^{2} - 16 x + 2 - 6

Subtract the numbers:

2 - 6 = - 4

= 11 x^{2} - 16 x - 4

\frac{( 2 )}{( 34 )}

- \frac{12}{24}

r, \frac{1}{3} + \frac{5}{3} r - r = 2 r

x, - 2 x - 6 > x + 9

x^{4} - 625
