Solve using the quadratic formula 3x^2=2 (2x+1) 3x2 = 2 (2x + 1) 3 x 2 = 2 ( 2 x + 1) move all terms to the left side of the equation and simplify. Tap for more steps. Use the quadratic formula to find the solutions.
Substitute the values a = 3. Use the quadratic formula to find the solutions. For ax2 +bx +c = 0, the values of x which are the solutions to the equation are given by:
X = −b ± √b2 −(4ac) 2 ⋅ a. X = −( −1) ± √( −1)2 − (4 ⋅ 3 ⋅ −1) 2 ⋅ 3. X = 1 ± √1 − ( −12) 6.
If a quadratic trinomial can be factored, this is the best solving method. If this is not the case, then it is better to use some other method. Algebra quadratic equations and functions quadratic formula.
1 answer nghi n. All equations of the form ax^{2}+bx+c=0 can be solved using the quadratic formula: The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
Quadratic equations such as this one can be solved by completing the square. In order to complete the square. X = −b ± √b2 −4ac 2a is the formula and a,b and c are found from ax2 + bx + c.
So in the given equation a = 3,b = 3 and c = 1. ⇒ x = −3 ± √32 − 4 × 3 × 1 2 × 3. ⇒ x = −3 ± √−3 6.
As you cannot take the square root of a negative number this means there is no solutions. This means the u shaped parabola is. Hope it helps you.
