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.
