प्रश्न

Verify whether the following are zeros of the polynomial, indicated against them, or not

p(x) = (x + 3) (x – 4), x = −3, x = 4

योग

उत्तर

p(x) = (x + 3) (x – 4), x = −3, x = 4

P(–3) = (–3 + 3) (–3 – 4)

= (0) (–7)

= 0

P(4) = (4 + 3) (4 – 4)

= (7) (0)

= 0

∴ – 3 and 4 are the zeros of the polynomial.
