Question

find the value of the polynomial, 6x-5x^2+30 at
(1)x=0
(2) x=√2

Answer 1

Answer:

1) 30

2) 2( 3root 2 + 10)

Step-by-step explanation:

Given , an polynomial

6x - 5x^2 + 30

1) value of polynomial at x =0

6(0) - 5(0)^2 + 30

= 0 - 0 + 30

= 30

2) value of plolynomial at x = root 2

6( root 2) - 5( root 2) ^2 + 30

= 6 root 2 - 10 + 30 [ (root 2)^2 = 2]

= 6 root 2 + 20

= 2 ( 3 root 2 + 10)
