Question

4xsquare + 4x - 3

(split the middle term)

Answer 1

Answer:

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

Step-by-step explanation:

Given that,

polynomial p(x) = 4x²+4x-3

Let,

p(x) = 0

⇒4x²+4x-3 = 0

(∵ the factors of 4(-3) = -12 to get their sum as 4 is 6 & -2 )

splitting ‘4x’ to ‘6x-2x’

⇒4x²+6x-2x-3 =0              (∵By rearranging the terms)

⇒4x²-2x+6x-3 = 0

⇒2x(2x-1)+3(2x-1) = 0

⇒(2x+3)(2x-1) = 0

Case-(1):                           Case-(2):

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

           ⇒2x = -3                             ⇒2x = 1

           ⇒x = -3/2                            ⇒x =1/2
