Q. 15


Find the sum and

Answer :


Let P(x) = 4x 2 – 7x
If a x 2 + bo x + c is the polynomial, then

Sum of the zeroes of the polynomial = -( b/a )
The product of the zeroes of the polynomial = ( c/a )

Here, a = 4, b = -7, c = 0

∴ Sum of zeroes of the given polynomial = -(-7/4) = 7/4

The product of zeroes of the given polynomial = (0/4) = 0.
