(s+5)(s-5)=s^2+2(s)(5)-5^2

(s + 5) (s - 5) = s^{2} + 2 (s) (5) - 5^{2}

s = 0

Solution steps

(s + 5) (s - 5) = s^{2} + 2 (s) (5) - 5^{2}

Remove parentheses:

(a) = a

(s + 5) (s - 5) = s^{2} + 2 s \cdot 5 - 5^{2}

Multiply the numbers:

2 \cdot 5 = 10

(s + 5) (s - 5) = s^{2} + 10 s - 5^{2}

5^{2} = 25

(s + 5) (s - 5) = s^{2} + 10 s - 25

Expand

(s + 5) (s - 5) : s^{2} - 25

s^{2} - 25 = s^{2} + 10 s - 25

Move

25

to the right side

s^{2} = s^{2} + 10 s

Subtract

s^{2} + 10 s

from both sides

s^{2} - (s^{2} + 10 s) = s^{2} + 10 s - (s^{2} + 10 s)

Simplify

- 10 s = 0

Divide both sides by

- 10

s = 0

x^{2} + 7 x = 30

(x - 16)^{2} = 12

x^{2} \geq - 1

2^{- 8}

9 x^{2} = 9 - 5 x
