Question

The zeros of the quadratic polynomial 4 x square - 4 x minus 3 are?

Answer 1

Answer:

Step-by-step explanation:

Let's solve it by Middle Term Splitting method.

4x²-4x-3.

Sum= -4.

Product= 4×-3= -12.

So the factors are 2 and -6.

4x²+2x-6x-3

2x(2x+1)-3(2x+1)

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

x=3/2,-1/2.

Answer 2

Answer:

Step-by-step explanation:

the given quadratic eq is

                                        = 4x²-4x-3

                                         =4x²-6x+2x-3

                                         =2x(2x-3)+1(2x-3)

                                          =(2x-3)(2x+1)

                                 ⇒  so the, 4x²-4x-3=0  ∴ (2x-3)(2x+1)=0

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

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

∴ hence the zeros of the given eq 4x²-4x-3=0 are 3/2 and -1/2
