expand (x-6)(sqrt(x+3)+3)

expand

(x - 6) (x + 3 + 3)

x x + 3 + 3 x - 6 x + 3 - 18

Solution steps

(x - 6) (x + 3 + 3)

Apply FOIL method

(x - 6) (x + 3 + 3) : x x + 3 + 3 x - 6 x + 3 - 18

= x x + 3 + 3 x - 6 x + 3 - 18

(a^{2} b - 12) + (- 8 a + 12 + 7 a^{2} b)

3 (\frac{5}{6})

- 3 x^{2} - 2 x

x^{2} + x^{2} + x^{2} + x^{2}

- 3 x^{2} + 9 x
