Example 18 find the discriminant of the equation 3x2 2x + 1/3 = 0 and hence find the nature of its roots. For f (x) = 4x 3 −3x 2 + 2x − 9 , what does descartes’ rule of signs tell you about. In order to find the multiplication of both the functions, it can be either done by first multiplying the expressions and then putting the value of x or first put the value of x in separate functions and then multiply them.
Factorise 2x3 x2 4x + 3. Brainly.in
Thinking process (i) firstly, find the prime factors of constant term in given polynomial.
Divide 2 in both sides.
(ii) substitute these factors in place of x in given polynomial and find the minimum factor which satisfies given polynomial and write it in the form of a linear polynomial. Use the quadratic formula to find the solutions. Add 2x to both sides. The axis of symmetry is x= and the vertex is 2 see answers advertisement advertisement mrroyal mrroyal the equation is an illustration of a quadratic function.

Check how easy it is, and learn it for the future. Substituting x = 2 in the given polynomial, we get Add 14 to both sides. Add 2 x to both sides.
X2 +(2 ⋅ ( 17 6)x) = 2 to make the middle term in the form of 2xy.
The solution is the pair that gives sum 17. Calculate the sum for each pair. Our solution is simple, and easy to understand, so don`t hesitate to use it as a solution of your homework. X2 +(2 ⋅ ( 17 6)x + (17 6)2 = 2 +( 17 6)2 = 361 36.
The solution is the pair that gives sum 1 7.
3(x2 + (17 3)x − 2) = 0. 3x2 + 17x −6 0#. Use the quadratic formula to find the solutions. For math, science, nutrition, history.
3 x + 2 = 1 7 − 2 x.
3x2 2x + 1/3=0 (3 3 2 3 2 + 1)/3=0 9x2 6x +1 = 0 3 9x2 6x + 1 = 0 comparing equation with ax2 + bx + c = 0 a = 9, b = 6 , c = 1 Move all terms containing x to the left, all other terms to the right. (x +(17 6))2 = ( 19 6)2. Rewrite 3 x 2 + 1 7 x + 1 0 as ( 3 x 2 + 2 x) + ( 1 5 x + 1 0).
