Question

What is zero of polynomial 2x^2+9x-5

Answer 1

Given : -

What is Zero of Polynomial 2x² + 9x - 5

Solution : -

➙ 2x² + 9x - 5

➙ 2x² + (10x - 1x) - 5

➙ 2x² + 10x - 1x - 5

➙ 2x (x + 5) -1 (x + 5)

➙ (2x - 1) (x + 5)

• x = 1/2
• x = 1/2 x = -5

Therefore , 1/2 and -5 are the zeroes of the Polynomial 2x² + 9x - 2 ....
