simplify 3(sqrt(x)-3)^2-4

simplify

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

3 x - 18 x + 23

Solution steps

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

Expand

(x - 3)^{2} : x - 6 x + 9

= 3 (x - 6 x + 9) - 4

Expand

3 (x - 6 x + 9) : 3 x - 18 x + 27

= 3 x - 18 x + 27 - 4

Subtract the numbers:

27 - 4 = 23

= 3 x - 18 x + 23

(- 4 x)^{0}

(3 - 4 i) + (- 12 - 3 i)

(3 x - 7) (2 x + 5)

2 (a + h)^{2} - (a + h) + 5
