simplify (7x^2-11+16x)+(5x-3x^2-7)

simplify

(7 x^{2} - 11 + 16 x) + (5 x - 3 x^{2} - 7)

4 x^{2} + 21 x - 18

Solution steps

(7 x^{2} - 11 + 16 x) + (5 x - 3 x^{2} - 7)

Simplify

(7 x^{2} - 11 + 16 x) + (5 x - 3 x^{2} - 7) : 7 x^{2} - 11 + 16 x + 5 x - 3 x^{2} - 7

= 7 x^{2} - 11 + 16 x + 5 x - 3 x^{2} - 7

Add similar elements:

16 x + 5 x = 21 x

= 7 x^{2} - 11 + 21 x - 3 x^{2} - 7

Group like terms

= 7 x^{2} - 3 x^{2} + 21 x - 11 - 7

Add similar elements:

7 x^{2} - 3 x^{2} = 4 x^{2}

= 4 x^{2} + 21 x - 11 - 7

Subtract the numbers:

- 11 - 7 = - 18

= 4 x^{2} + 21 x - 18

\frac{2}{7} \cdot \frac{9}{8}

- \frac{14}{25} - (- \frac{9}{10})

(\frac{14 x ^{2} y}{7 x z})^{- 3}

\frac{1 8 ^{5}}{9 ^{5}}

\frac{2 ( - x ) ^{2} - 1}{( - x ) ^{2}}
