Langkah pertama tentukan titik. x + y ≤ 6.Algebra Solve Using the Quadratic Formula 2x^2-6x+1=0 2x2 − 6x + 1 = 0 2 x 2 - 6 x + 1 = 0 Use the quadratic formula to find the solutions. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a Substitute the values a = 2 a = 2, b = −6 b = - 6, and c = 1 c = 1 into the quadratic formula and solve for x x.2x2-6x-16=0 Two solutions were found : x = (3-√41)/2=-1.702 x = (3+√41)/2= 4.702 Step by step solution : Step 1 :Equation at the end of step 1 : (2x2 - 6x) - 16 = 0 Step 2 : Step 3 ... 3x2-6x-16=0 Two solutions were found : x = (6-√228)/6=1-1/3√ 57 = -1.517 x = (6+√228)/6=1+1/3√ 57 = 3.517 Step by step solution : Step 1 :Equation at ... Equation at the end of step 1 (2x2 - 6x) - 1 = 0 . STEP. 2: Trying to factor by splitting the middle term. 2.1 Factoring 2x2-6x-1 . The first term is, 2x2 its coefficient is 2 . The middle term is, -6x its coefficient is -6 . The last term, "the constant", is -1 . Step-1 : Multiply the coefficient of the first term by the constant 2 • -1 = -2Example: 3x^2-2x-1=0 (After you click the example, change the Method to 'Solve By Completing the Square'.) Take the Square Root. Example: 2x^2=18. Quadratic Formula. Example: 4x^2-2x-1=0. About quadratic equations Quadratic equations have an x^2 term, and can be rewritten to have the form: a x 2 + b x + c = 0. Need more problem types? It isn't easy to immediately see how $2x^2-1$ can factor (or if it can) but $2x^2 - 1 \equiv 2x^2 + 6\equiv 2(x^2 +3)$ so if we can find $-k^2 \equiv 3\pmod 7$ we can have a difference of squares. $3 \equiv -4.. $ and ... that was quick. So $2x^3+5x^2 + 6x + 1\equiv (2x^2-1)(x-1)$ $\equiv 2(x^2+3)(x-1)\equiv 2(x^2 -4)(x-1)$ $\equiv 2(x+2)(x-2 ...3.2 Solving 3x2-6x+1 = 0 by Completing The Square . Divide both sides of the equation by 3 to have 1 as the coefficient of the first term : x2-2x+ (1/3) = 0. Subtract 1/3 from both side of the equation : x2-2x = -1/3. Now the clever bit: Take the coefficient of x , which is 2 , divide by two, giving 1 , and finally square it giving 1.Algebra. Solve by Completing the Square 2x^2+6x+3=0. 2x2 + 6x + 3 = 0. Subtract 3 from both sides of the equation. 2x2 + 6x = - 3. Divide each term in 2x2 + 6x = - 3 by 2 and simplify. Tap for more steps... x2 + 3x = - 3 2.
