To evaluate the integral using the trapezium rule with eight ordinates, we first need to determine the strip width h. The integral is _1.2^4.4 (2x^2 + 3x - 1)/(sqrt(x+2)) dx. Let f(x) = (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. h =
