Question

2x^2+5x-3please solve this​

Answer 1

Answer:

split 5x as 2x and 3 x. you will get x+1 and 2x - 3 as answers

so x = -1 or 3/2

Answer 2

Answer:

x=1/2 (or) x=-3

Step-by-step explanation:

Given that,

2x²+5x-3 is the equation of polynomial p(x)

p(x)=2x²+5x-3=0

⇒2x²+5x-3=0        (Here to factorise any eq. ax²+bx+c we must find the factors                                    

                                                                        of a×c)

⇒2x²+5x-3=0             (∵The factors of 2×-3=-6 is to get their sum as 5 is 6 & -1)

⇒2x²+6x-x-3=0

⇒2x(x+3)-(x+3)=0

⇒(2x-1)(x+3)=0

case-(1)                            Case-(2)      

         ⇒2x-1=0                            ⇒x+3=0

         ⇒2x=1                                ⇒x=-3

         ⇒x=1/2      

∴x=1/2 (or) x=-3
