Activity $2=$ Finding the Number of Roots of Polynomial Equations
Some polynomial equations are given below. Complete the table and answer
the questions that follow. (If a root occurs twice, count it twice; if thrice, count
it three times, and so on. The first 'one is done for you)
Polynomial Equation Degree Real Roots of Number of
an Equation Real Roots
$1$ $\left(x+1\right)^{2}\left(x-5\right)=0$ $-1\left(2$ times); 5 3
$2.$ $x-8=0$
$3$ $\left(x+2\right)\left(x-2\right)=0$
$4$ $\left(x-3\right)\left(x+1\right)\left(x-1\right)=0$
$5$ $x\left(x-4\right)\left(x+5\right)\left(x-1\right)=0$
$6$ $\left(x-1\right)\left(x-3\right)^{3}=0$
$7.$ $\left(x^{2}-4x+13\right)\left(x-5\right)^{3}=0$
$8.$ $\left(x+1\right)^{5}\left(x-1\right)^{2}=0$
$9.\left(x^{2}+4\right)\left(x-3\right)^{3}=0$
$10.\left(x-\sqrt{2} \right)^{6}\left(x+\sqrt{2} \right)^{6}x^{4}=0$

with solution pleaseSolution

Qanda teacher - Madhukar

Student

thank u ma'am can u send the solution on how did u solve that

Qanda teacher - Madhukar

except for 7th and 9th everything is similar just equate them to the zero

Student

ok ma'am noted

ma'am where's the solution :)

or computation of that

Qanda teacher - Madhukar

did u understand how to do the remaining

Student

no ma'am but thank you i really appreciated it

Qanda teacher - Madhukar

just equate them to the zero like in the above examples

most welcome

Student

yes ma'am thank you i will?❤️

ma'am I'm just wondering of what is the solution/computation of 2,3,4,5,6,8,10
