Step-by-step explanation:
1. (2a + 5) + (40² + 2a-5)
Ans.
[tex]4 • (a + 400)[/tex]
Solution.
40 = 23•5
(40)2 = (23•5)2 = 26 • 52
(2a + 5) + (26•52) + 2a) - 5)
Pulling out like terms
Pull out like factors :
4a + 1600 = 4 • (a + 400)
2. ( -26xy²) + (22y²x)
Ans.
[tex]-4xy {}^{2} [/tex]
Solution.
Just pull out like terms
