Question

can someone show me the steps to get this answer-

Multiply out (2a-5)^2 and collect terms.

Answer 1

Simply,

(2a - 5)(2a - 5)

Use FOIL to silve.

Answer 2

Answer 3

Square the first term: 4a^2
Multiply the 2a * -5 then double it so: 2a *-5 *2= -20a
Square the third term: 25
Now add them. 4a^2 -20a + 25

Answer 4

4a^2 -20a + 25
16 - 20a = 25
4a + 25
29a

is that how to add it up ?
