expand 7(x^2+4-4ln|x^2+4|)

expand

7 (x^{2} + 4 - 4 ln x^{2} + 4)

7 x^{2} + 28 - 28 ln x^{2} + 4

Solution steps

7 (x^{2} + 4 - 4 ln x^{2} + 4)

Distribute parentheses

= 7 x^{2} + 7 \cdot 4 + 7 (- 4 ln x^{2} + 4)

Apply minus-plus rules

+ (- a) = - a

= 7 x^{2} + 7 \cdot 4 - 7 \cdot 4 ln x^{2} + 4

Multiply the numbers:

7 \cdot 4 = 28

= 7 x^{2} + 28 - 28 ln x^{2} + 4

\frac{d}{d x} (x^{2} + 3 x + 3) + (2 x + 3) x

(11.37) 0.9

\frac{( 6 x ^{2} + x + 3 )}{( x + 1 ) ( x ^{2} + 1 )}

\frac{x + y}{x y} - \frac{x + 2 y}{x y + y ^{2}} - \frac{y}{x ^{2} + x y}

(1 + y cos (x)) d x - sin (x) d y
