SOLVING QUADRATIC EQUATIONS
2) Solve 2x2 - 5 = 27

x = ±4

Step-by-step explanation:

Step 1: Write out quadratic

2x² - 5 = 27

Step 2: Add 5 to both sides

2x² = 32

Step 3: Divide both sides by 2

x² = 16

Step 4: Take the square root of both sides

x = ±4

∴ x can equal -4 or 4

Step by step explanation:

Given Equation is :-

We need to find the value of using Quadric formula.

Firstly, Subtract 27 from both of the side(s):-

On Simplification:-

Add -5-27 as (-) and (-) equals to (+). -5-27 would be represented as 5+27, which results to 32.

Then, for this equation , a=2, b=0, c=-32.

Put the values :-

That is,

As we know, that the quadratic formula is:-

Put the values :-

On Simplification:-

As 0 has no value here,

On cancelling,

Remove the square of 256 ( √256)

It may be represented as,

Or,
