integral from 0 to 3 of sqrt(4-4x+x^2)

\int_{0}^{3} 4 - 4 x + x^{2} d x

\frac{5}{2}

Decimal

2.5

Solution steps

\int_{0}^{3} 4 - 4 x + x^{2} d x

Factor

4 - 4 x + x^{2} : (x - 2)^{2}

= \int_{0}^{3} (x - 2)^{2} d x

Apply exponent rule:

a^{2} = ∣ a ∣

= \int_{0}^{3} (x - 2)^{2} d x

Eliminate Absolutes

= \int_{0}^{2} (x - 2)^{2} d x + \int_{2}^{3} (x - 2)^{2} d x

\int_{0}^{2} (x - 2)^{2} d x = 2

\int_{2}^{3} (x - 2)^{2} d x = \frac{1}{2}

= 2 + \frac{1}{2}

Simplify

2 + \frac{1}{2} : \frac{5}{2}

= \frac{5}{2}
