simplify (3-sqrt(x))(3-sqrt(x))

simplify

(3 - x) (3 - x)

9 - 6 x + x

Solution steps

(3 - x) (3 - x)

Apply exponent rule:

aa = a^{2}

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

= (3 - x)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(3 - x)^{2} = 3^{2} - 2 \cdot 3 x + (x)^{2}

= 3^{2} - 2 \cdot 3 x + (x)^{2}

3^{2} = 9

- 2 \cdot 3 x = - 6 x

(x)^{2} = x

= 9 - 6 x + x

, e^{- α^{2} k^{2} t}

3.5 \times 1 0^{- 5}

(b^{11} d^{9} z^{7}) (d r^{4} z^{18}) (a^{2} b^{9} z)

\frac{3}{14} \cdot \frac{14}{14}

1 - x \times 1 + x
