((1+kx))^(1/3) +x = 1 has two real roots . ⇒ k=? kx+1= 1−3x+3x^2 −x^( 3) x^( 3) −3x^( 2) + (k+3)x=0 x=0 x^( 2) −3x +k+3=0 1: Δ=0 9 − 4k −12=0 k= ((−3)/4) 2: k=−3 ⇒ x=0 is a root of x^( 2) −3x+k+3=0 ∴ k= ((−3)/4) or k=−3

$\sqrt[3]{1 + k x} + x = 1 h a s$ $t w o r e a l r o o t s . \Rightarrow k = ?$ $k x + 1 = 1 - 3 x + 3 x^{2} - x^{3}$ $x^{3} - 3 x^{2} + (k + 3) x = 0$ $x = 0$ $x^{2} - 3 x + k + 3 = 0$ $1 : Δ = 0$ $9 - 4 k - 12 = 0$ $k = \frac{- 3}{4}$ $2 : k = - 3 \Rightarrow x = 0 i s a r o o t o f$ $x^{2} - 3 x + k + 3 = 0$ $∴ k = \frac{- 3}{4} o r k = - 3$

Explanation Why: While f(ax+b)+f(cx+d)=ex+g then f(x)=Ax^2 +Bx+C ¿

$E x p l a n a t i o n W h y :$ $W h i l e f (a x + b) + f (c x + d) = e x + g$ $t h e n f (x) = {A x}^{2} + B x + C ¿$

lim_( x→ 0^( −) ) { (( x^( 2) +2cos(x) + ⌊−((tan(x))/x) ⌋)/(ax^( 4) )) } = 1 a = ? a: (1/(12)) b: −(1/2) c: 12 d: −12

$\lim_{x \to 0^{-}} {\frac{x^{2} + 2 c o s (x) + ⌊ - \frac{t a n (x)}{x} ⌋}{{a x}^{4}}} = 1$ $a = ?$ $a : \frac{1}{12} b : - \frac{1}{2} c : 12 d : - 12$
