Question

solve the equation: 1/2x^2 - root11x + 1 =0 ​

Answer 1

→ The first term is,  2x2  its coefficient is  2 .

→ The middle term is,  +x  its coefficient is  1 .

→ The last term, "the constant", is  -1  

⊕ Step-1 : Multiply the coefficient of the first term by the constant   2 • -1 = -2  

⊕ Step-2 : Find two factors of  -2  whose sum equals the coefficient of the middle term, which is   1 .

→     -2    +    1    =    -1  

   →  -1    +    2    =    1    That's it

⊕Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -1  and  2

→                    2x2 - 1x + 2x - 1

⊕Step-4 : Add up the first 2 terms, pulling out like factors :

→                    x • (2x-1)

 →            Add up the last 2 terms, pulling out common factors :

                    1 • (2x-1)

⊕Step-5 : Add up the four terms of step 4 :

→                   (x+1)  •  (2x-1)

 →           Which is the desired factorization

⊕ Equation at the end of step

3

:

→  (1 - 2x) • (x + 1)  = 0
