Question

the roots of 2x² - 8 = 0 are

Answer 1

To Find :-

• Roots of the equation

Answer :-

• $\pm$2

Solution :-

• No of roots open any equation is equal to the the power of the variable given into the equation

• In, this equation the power of variable is to show the the given equation has two roots

${}$

$\sf{2\ x^{2}-8=0}$

${}$

$\sf{2\ x^{2} = 8}$

${}$

$\sf{\ x^{2} = \dfrac{8}{2}}$

${}$

$\sf{\ x^{2} = 4}$

${}$

$\sf{x = \sqrt{4}}$

${}$

$\sf{x = \pm 2}$

${}$

So , the roots of the given equation are +2 and -2
