Answer 1

Solution

Given :-

• Equation , 4x² - 49 = 0

Find :-

• roots of this Equation

Explanation

Given that,

==> 4x² - 49 = 0

==> 4x² = 49

==> x² = 49/4

==> x = ±√(49/4)

==> x = ± 7/2

In means that,

Here two roots of this Equation.

• First be x = 7/2
• Second be x = -7/2

Hence

• Roots will be = 7/2 , -7/2
