simplify-17+(-7)*x^2-(-31)

simplify

- 17 + (- 7) \cdot x^{2} - (- 31)

- 7 x^{2} + 14

Solution steps

- 17 + (- 7) x^{2} - (- 31)

Apply rule:

a - (- b) = a + b

(- 7) x^{2} - (- 31) = (- 7) x^{2} + 31

= - 17 - 7 x^{2} + 31

Group like terms

= - 7 x^{2} - 17 + 31

Add the numbers:

- 17 + 31 = 14

= - 7 x^{2} + 14

(2 x + 2)^{3} + (x - 3)^{3}

- x^{3} - 3 x + 1 + 3 x^{2}

(- 2 x^{3} y^{3} z^{2}) (- 2 x^{2} y^{4} z^{2})^{2}

(144 k^{2} r^{14})^{\frac{1}{2}}

(y + 5)^{3}
