expand (45du-8)(45du+8)

expand

(45 d u - 8) (45 d u + 8)

2025 d u^{2} - 64

Solution steps

(45 d u - 8) (45 d u + 8)

Apply Difference of Two Squares Formula:

(a - b) (a + b) = a^{2} - b^{2}

a = 45 d u, b = 8

= (45 d u)^{2} - 8^{2}

Simplify

(45 d u)^{2} - 8^{2} : 2025 d u^{2} - 64

= 2025 d u^{2} - 64

\frac{\partial}{\partial x} ((M) (1 + y (M, x)))

\frac{x ^{2} + ( y - 1 ) ^{2}}{x ^{2}}

\frac{2500 s ( 20 s + 200 )}{( s + 1 ) ( s ^{2} + 100 s + 10000 )}

\frac{( x - 2 ) ( x - 4 )}{4}

- \frac{( - x + 2 ) ^{2}}{4}
