Answer 3

To simplify the expression (х – 4)(х + 4) – х(х – 5), let's expand it and simplify the terms:

(х – 4)(х + 4) – х(х – 5)

Expanding the first parentheses: = (х * х) + (х * 4) + (-4 * х) + (-4 * 4) – х(х – 5)

= х^2 + 4х - 4х - 16 – х(х – 5)

Simplifying like terms: = х^2 - 16 – х(х – 5)

Distributing х to the terms inside the parentheses: = х^2 - 16 – (х^2 - 5х)

Removing the parentheses: = х^2 - 16 - х^2 + 5х

Combining like terms: = 5х - 16

Therefore, the simplified form of the expression (х – 4)(х + 4) – х(х – 5) is 5х - 16.
