QUADRATIC POLYNOMIAL=2x²+5x-3
WE CAN FIND THE ROOTS OF THE POLYNOMIAL TROUGH TWO WAYS.
1.USING QUADRATIC FORMULA
2.SPLITTING THE MIDDLE TERM
2x²+5x-3=0
WE HAVE TO SPLIT THE MIDDLE TERM IN SUCH A WAY THAT ITS PRODUCT HAS TO BE EQUAL TO THE CONSTANT TERM.
AS THE x² CO-EFFICIENT IS 2 WE HAVE TO MULTIPLY IT WITH THE CONSTANT THAT IS -3.BUT THIS STEP SHOULD NOT BE WRITTEN IN THE ANSWER WE HAVE TO KEEP IT IN OUR MIND.
2x²+5x-3=0
2x²+6x-1x-3=0(here 6x-1=6 which is equal to the product of 2 and -3)
TAKE COMMON,
2x(x+3)-1(x+3)=0
(x+3)(2x-1)=0
NOW EQUAL THEM TO ZERO,
x+3=0
x=-3
2x-1=0
x=1/2
THEREFORE -3,1/2 ARE THE ROOTS.
