WebSo I'm trying to solve the following equation for x: sqrt(x+3)-sqrt(2x+4)+1=0 From what I can find, the solution is x = 6. Wolfram alpha and my textbook support this. ... 1: sqrt(x+3)-sqrt(2x+4)+1=0 2: subtract 1 and add sqrt(2x+4) which results in sqrt(x+3)=-1+sqrt(2x+4) 3: square both sides which results in x+3=-2(sqrt(2x+4)) ...

Consider the following. x = 5 − 2t, y = 2 + 5t

WebJust multiply both sides by x^2 to get -1+2x^3=0, then you get 2x^3-1=0 by commutivity. What is the value of a^3+b^3+c^3 if a,b,c are the roots of 3x^3-1=0? ... Divide x^{3}-1 by x-1 … WebFirst, let's calculate f (8) using the function f (x): f (x) = 3x^3 - 2x + 7 f (8) = 3 (8)^3 - 2 (8) + 7 f (8) = 1535. Next, let's calculate h (8) using the function h (x): h (x) = x^2 - x + 1 h (8) = (8)^2 - 8 + 1 h (8) = 57. Now we can substitute these values into the equation f (8) = g (8)h (8) + r (8) and solve for g (8) and r (8). WebSince, f(x) is a rational integral function of x, therefore it is continuous and differentiable for all real values of x. Hence, the first two conditions of Rolle's theorem are satisfied in any … raymonds l2sofa
