If h(x) = 3x²–2x²+ Kx-5 is divided
sergij07 [2.7K]

Let f(x)=x3(exponent)+kx2(exponent)+x+5

When f(x) is divided by (x+2) the remainder is =3

This is the remainder theorem

so,f(−2)=−8+4k−2+5=3

4k=3+5=8

k=2

G(x) = 3x -1. Find x such that g(x)= 2​​0​.
sergiy2304 [10]

Step-by-step explanation:

i. 3x-1=20

or, 3x= 21

x= 7

ii. 3x+1= 22

3x= 21

x= 7

iii. 2x-5=99

2x= 104

x=52

iv. g(3)= 3+5/2= 11/2

g(0)= 0+ 5/2=5/2

g(-3)= -3+5/2 = -1/2

x+5/2= 0

so, x= -5/2
