Question

(v) p(x) = 3x^2+ 5x - 7 at x = 1​

Answer 1

Answer:

answer is 1

Step-by-step explanation:

p(x) = 3x² + 5x - 7

at x = 1

p(1) = 3(1)² + 5(1) - 7

= 3 + 5 - 7

= 8 - 7

= 1

Answer 2

Answer :-

The remainder is 1

$\bf\huge\underline\purple{Solution}$

p(x) = 3x² + 5x - 7

and the value of x is 1

From the remainder thereom, we know that p(1), Now :-

Putting the value of x, we get:-

3x² + 5x - 7

= 3.(1)² + 5.1 - 7

= 3.1 + 5 - 7

= 3 + 5 - 7

= 8 - 7

= 1

Hence, the remainder is 1
