simplify 8^3-11+5[7x+2-2(7+3x)]+7^2

simplify

8^{3} - 11 + 5 [7 x + 2 - 2 (7 + 3 x)] + 7^{2}

5 x + 490

Solution steps

8^{3} - 11 + 5 (7 x + 2 - 2 (7 + 3 x)) + 7^{2}

8^{3} = 512

7 x + 2 - 2 (7 + 3 x) = x - 12

7^{2} = 49

= 512 - 11 + 5 (x - 12) + 49

Expand

5 (x - 12) : 5 x - 60

= 512 - 11 + 5 x - 60 + 49

Group like terms

= 5 x + 512 - 11 - 60 + 49

Add the numbers:

512 - 11 - 60 + 49 = 490

= 5 x + 490

x (x - 2) (x + 3)

\frac{2 x - 10}{x + 8} \cdot \frac{x ^{2} - 64}{x ^{2} + 3 x - 40}

- x (x)

x^{2} + 1^{2}

\frac{3}{- 1}
