To evaluate the integral using the trapezium rule with eight ordinates, we first need to determine the strip width h.

To evaluate the integral using the trapezium rule with eight ordinates, we first need to determine the strip width $h$.
The integral is $\int_{1.2}^{4.4} \frac{2x^2 + 3x - 1}{\sqrt{x+2}} dx$.
Let $f(x) = \frac{2x^2 + 3x - 1}{\sqrt{x+2}}$.
The lower limit is $a = 1.2$ and the upper limit is $b = 4.4$.
The number of ordinates is 8, which means the number of strips $n = 8 - 1 = 7$.

Step 1: Calculate the strip width $h$.
