Question

Find the value of the polynomial 3x2 + 5x -2

(i) x = 0 (ii) x = -1 (iii) p(x) = 2​

Answer 1

Answer:

Hey buddy the correct answer is ( ii ) x = - 1 .

Step-by-step explanation:

= 3x² + 5x - 2

= 3x² + 3x + 2x - 2

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

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

Therefore , x = - 1 or x = - 2 / 3

Here , option given is ( ii ) x = - 1 .

So , ( ii ) is correct .
