Question

find all the zeroes of the polynomial 2x²+7x-15 and verify the relationship between the coefficients. ​

Answer 1

Answer:

Hi friends

Step-by-step explanation:

2x² -10x +3x - 15 = 0

→ 2x(x - 5) + 3(x - 5) = 0

→ (2x + 3)(x - 5) = 0

Putting Both Equal to Zero now, we get,

→ 2x + 3 = 0

→ 2x = -3

→ x = (-3/2)

Or,

→ x - 5 = 0

→ x = 5

Hence, Zeros of The polynomial are 5 and (-3/2).
