Question

zeros of 2x²+5x-3 someone help me ​

Answer 1

Step-by-step explanation:

Given :-

2x²+5x-3

To find :-

Find the zeroes of the polynomial ?

Solution :-

Given polynomial is 2x²+5x-3

Let P(x) = 2x²+5x-3

=> 2x²-x+6x-3

=> x(2x-1)+3(2x-1)

=> (2x-1)(x+3)

To get zeroes of P(x) then we write it as P(x) = 0

=> P(x) = 0

=> (2x-1)(x+3) = 0

=> 2x-1 = 0 or x+3 = 0

=> 2x = 1 or x = -3

=> x = 1/2 or x = -3

Therefore, x = 1/2 or -3

Answer:-

The zeroes of P(x) are 1/2 and -3
