expand sqrt((1+8(2x^2-x)))

Solution

expand

(1 + 8 (2 x^{2} - x))

Solution

4 x - 1

Solution steps

1 + 8 (2 x^{2} - x)

Expand

1 + 8 (2 x^{2} - x) : 1 + 16 x^{2} - 8 x

= 1 + 16 x^{2} - 8 x

Factor

16 x^{2} - 8 x + 1 : (4 x - 1)^{2}

= (4 x - 1)^{2}

Apply radical rule:

assuming

a \geq 0

= 4 x - 1
