Question

find the zero of 2xsquare-3+5x verify the relationalship between the zeroes and co efficients​

Answer 1

Solution :

→ 2x² +5x -3 = 0

→ 2x² + 6x - x - 3 = 0

→ 2x ( x + 3) - 1 ( x + 3 ) = 0

→ ( 2x - 1 ) ( x + 3 ) = 0

→ α = 1/2

→ β = - 3

verification of relationalship between the zeroes and co efficients

α + β = - b/a

→ 1/2 - 3 = - 5/2

→ - 5/2 = - 5/2

αβ = c/a

→ 1/2 × ( - 3 ) = - 3/2

→ - 3/2 = - 3/2
