The table shown shows the heights of voices.
To get the tallest height you calculate the mean of each voice.
Mean height of soprano;
(60+62+62+64+65+65+66+66+67+68)/10 = 645/10 =64.5
Mean height of alto;
(60+61+62+63+64+65+66+69+70+72)/10 =592/10 =59.2
Mean height of tenor;
(64+66+66+67+68+70+72+73+74+76)/10 = 550/10 =55
mean height of Bass;
(66+68+68+69+70+70+71+72+73+75)/10 = 702/10 =70.2
The two voice parts that have the tallest singers are Soprano and Bass.
These is because the two voices have the highest average height.

Step-by-step explanation:
It appears to be the last step there that has evaded you. In the second line of work, you can see that what's in each set of parenthesis is exactly the same. Because of this, it is common and can be factored out. What's left is the 4x and the +5:
(5x - 3)(4x + 5)
That's factoring by grouping. It only works with polynomials that have an even number of terms so you can group them together in 2's.
