Solve the equation 2x^3-5x^2+x+2=0 given that 2 is a zero of f(x)= 2x^3-5x^2+x+2
zalisa [80]

The polynomial equation 2x^{3} - 5 x^{2} + x + 2 = 0 given that 2 is zero of

f(x) = 2x^{3} - 5 x^{2}  + x +2

According to the question,

f(x)  =2x^{3} - 5 x^{2} + x + 2

f(2)= 2(2)^{3} - 5 (2)^{2} + 2 + 2 \\= 2(8) - 5(4) +4\\= 16 - 20 + 4\\= -4 + 4\\= 0.

Hence, the polynomial equation 2x^{3} - 5 x^{2} + x + 2 = 0 given that 2 is zero of f(x)  =2x^{3} - 5 x^{2} + x + 2.

If f(x) is a linear function, what is the value of n?
Viefleur [7K]

m = (-10 + 25)/(-1 + 4) = 15/3 = 5

so

5 = (20 + 10)/(n + 1)

5(n+1) = 30

5n + 5 = 30

5n = 25

n = 5

Answer

n = 5
