N (xr)=\N(x)]r. = 0 and x2. ~. 2.vu x = 0. Hence. ; zzr (2*0 ) xr-'. = (2x 0 ) r - 1 x = 0 and. Let. A-2 — c where c B F . Then c — 2xv x + N(x) — 0 and. I f x ... Solution: We check for the critical points in the interior fx = 2x, fy = 2(y +1) =⇒ (0,−1) is a critical point . The second derivative test fxx = 2,fyy = 2,fxy ... x 2x + 2 2x. 3 + 2x2. 2x. = 66. 50 = 74. a2 = 67. 3 12 = 75. a3 = 68. 54. 3. = 76 ... ( )= 0 and thus, x = 3 or x = −2. Note: there must be a zero on one ... Dec 14, 2016 ... x = 0 and x = -2 You can factor x^2 + 2x = 0 as: x(x + 2) = 0 Now, we can solve each term for 0: x = 0 - no other work needed, and x + 2 = 0 ... Learn a Fact: 0 x 2. Follow steps 1-6 to master this fact. Multiplication by ZERO is super simple. Any number times zero is ZERO. c) 2 + x2)~/x 2 - 2(rex + c)kx 2 - (:t:x2 V/1 - 4(mx + c)k - 4k2x 2) m ... over the edges for lmes (a) 2/ = 2x - 0 2, (b) y = x - 0 2, (c). 9 = 0 4x - 0 ... 0 < √2 − y. 2x0. = z2(x2 − 2). 2x0 (2x0+1/2 + y). < z2(x2. 0 + x0). 22x0−3 ...
