Answer:

x3(x+1)= –2(x-1)–4

3x^2+3x=–2x+2-4

3x^2+3x+2x=2-4

3x^2+5x=–2

3x^2+5x+2=0

3x^2+3x+2x+2=0

3x(x+1)2(x+1)=0

(3x+2)(x+1)=0

3x+2=0 or x+1=0

3x=–2 or x=–1

x=–2/3 or –1

Step-by-step explanation:

–remove brackets by multiplication

–form a quadratic equation

–and then solve either by means of quadratic formula or factorisation method

Find the zeros of the polynomial p(x) 5-10x​
Charra [1.4K]

Answer:

Step-by-step explanation:

The given polynomial is :

p(x) = 5-10x​

We need to find the zeros of the above polynomial. To find it, put p(x) = 0

5-10x​ = 0

Subtract 5 from both sides

5-10x​-5=0-5

-10x=-5

or

10x=5

Divide both sides by 10.

x = 0.5 = 1/2

Hence, the zeros of the polynomial is 1/2.
