Nếu một phương trình bậc hai vô nghiệm thì parabol tương ứng có đặc điểm gì với trục hoành?

(x) = 8x. Con- nuing on, we have f. ′′. (x) = d dx. (. 8x. ) = 8; f. ′′′. (x) ... f(x)=(x − 2)2 ln(x − 2). 18. f(x) = x2 − 4 x2. 19. f(x) = x2 − 4x + 3 x2 ... (b) x″ + 8x′ + 7x = f(t), where f(t) = F0 cos(𝜔t). 9.2. Do ... (d) x′ = (2 − x)3. 12.2. Consider y′ = y(y−a−1)(y−2a), where a ... We can now square root both sides to give: x+4=0. Now subtracting 4 from both sides gives x=-4. This means that for x^2+8x+16=0 we have found that x=-4. Click here to see ALL problems on Inequalities · Question 330857: x2 - 8x + 16 >= 0. I got x=4 as the answer but I keep getting told it wrong. \displaystyle -2 and whose product is \displaystyle 3 \left ( -16 \right ) = -48; these numbers are \displaystyle -8,6. \displaystyle 3x^{2} -8x + 6x - 16 = 0. x(8x + 4nr-16) ) x2 + 2(-4)x _ (n-4) 2 (n+) 0. 4- 2(n +4) 2(4- 2(n+4)).
