Question

If -1 is a zero of the polynomial 2 x cube minus x square - 5 x minus 2 find the other zeros

Answer 1

Answer:

Step-by-step explanation:

P(x) =2x³-x²-5x-2

Here,

X= -1

So , x+1=o

Is a factor

Now,

Divide the factor with p(x)

The quotient will be 2x²-3x-2

Now,

D= b²-4ac

D=3²-4(2)(-2)

D= 9+16

√D =+-5

X= - b+- √D÷2a

So x=2 and x= -1/2

Answer 2
