Question

find the value of given polynomial at given value of variable. with explanation

1.R(x)=10-x at x=5 and ×=4
2.S(x)=100=x² at x=10 and x=5
3.T(x)=x²+12x-10 at x=(-3)
​

Answer 1

Step-by-step explanation:

1. at x= 5, R(5) = 10-5 = 5

at x= 4, R(x) = 10 - 4 = 6

2. at x= 10, S(x) = 100 -10² = 100-100 =0

at x= 5,S(x) = 100 - 5² = 100- 25 = 75

3. T(x) x² + 12x - 10

at x = -3, T(x) = (-3)² + 12×(-3) -10

T(x) = 9 - 36 -10

T(x) = -37
