3x^{2} +1=28

Step 1 : subtract 1 from both sides

3x^{2} =27

Step 2 : Divide both sides by 3

\frac{\frac{3x^{2} }{3} }{\frac{27}{3} }

x^{2} = 9

Step 3 : Find the square root of 9

\sqrt{9} = 3

x= (-3,3)

remember negative × negative = positive

(x - 1)2 = 4<br> how do i do this
Gnoma [55]

Answer:

x = 3

Step-by-step explanation:

(x - 1)2 = 4

how to get this solved is very simple.

first step to apply is the BODMAS RULE

B..................... bracket

O..................... of

D.....................Division

M.................... multiplication

A..................... addition

S.................... Subtraction

so (x - 1)2 = 4

we have,

2x - 2 = 4 ( by opening the bracket)

collect the like terms

2x = 4+2

divide both sides by 2

2x/2 = 6/2

x = 3

to check if your answer is correct put the value of x = 3 into the question and see if the right hand side will equal to the left handside

(x - 1)2 = 4

(3-1)2=4

2(2)=4

4=4.............................. proved
