Question

Factorise4x square -x-3

Answer 1

Answer:

4x²

Step-by-step explanation:

4x²-x-3

=4x²-4x+3x-3

=4x(x-1)+3(x-1)

=(4x+3)(x-1)

hence x=-¾ or x=1

Answer 2

Answer:

4x² - x - 3

Take two numbers whichbon multiplying come 12 and on adding it comes (-1)

So ,

4x² -4x+3x -3

4x(x-1)+3(x-1)

(4x+3)(x-1)

If you want the value of X, than it will be

(4x+3)(x-1)=0

There will be two answers

4x+3 =0

4x= -3

X= -3/4-----> (I)

x-1=0

x=1

As the negative number will be will be not taken ..

So the answer is 1
