simplify-4x+x^2-3x-5+7x^2tt

simplify

- 4 x + x^{2} - 3 x - 5 + 7 x^{2} tt

x^{2} - 7 x + 7 x^{2} t^{2} - 5

Solution steps

- 4 x + x^{2} - 3 x - 5 + 7 x^{2} tt

Group like terms

= x^{2} - 4 x - 3 x + 7 x^{2} tt - 5

Add similar elements:

- 4 x - 3 x = - 7 x

= x^{2} - 7 x + 7 x^{2} tt - 5

Apply exponent rule:

aa = a^{2}

tt = t^{2}

= x^{2} - 7 x + 7 x^{2} t^{2} - 5

(2 a + b)^{3} - (2 a - b)^{3} - 6 b (2 a + b) (2 a - b)

(t^{3} + 1)^{3}

f (x) 2 x^{2} + 5 x - 7

[x 1 - 4 x^{2}]^{2}

- 8 (1 - 2 x) - 5 (2 x - 6)
