simplify (2s+1)(2s+9)-(2s)^2

Solution

simplify

(2 s + 1) (2 s + 9) - (2 s)^{2}

Solution

20 s + 9

Solution steps

(2 s + 1) (2 s + 9) - (2 s)^{2}

Simplify

(2 s)^{2} : 4 s^{2}

= (2 s + 1) (2 s + 9) - 4 s^{2}

Expand

(2 s + 1) (2 s + 9) : 4 s^{2} + 20 s + 9

= 4 s^{2} + 20 s + 9 - 4 s^{2}

Group like terms

= 4 s^{2} - 4 s^{2} + 20 s + 9

Add similar elements:

4 s^{2} - 4 s^{2} = 0

= 20 s + 9
