Am I correct? (Perfect Square Form)
natka813 [3]

Answer:

(x -3 )^2 = 10

Step-by-step explanation:

Given

x^2 - 6x - 1 = 0

Required: Express as a perfect square

x^2 - 6x - 1 = 0

Add 10 to both sides

x^2 - 6x - 1 +10= 0+10

x^2 - 6x +9= 10

Expand

x^2 - 3x  - 3x+9= 10

Factorize:

x(x - 3) - 3(x  - 3)= 10

Factorize:

(x -3 )(x - 3) = 10

(x -3 )^2 = 10

Three-fourths of a number increased by one-half is equal to fourteen. Find the number.
ivanzaharov [21]

Three-fourths of a number increased by one-half

= 3/4 x + 1/2

So three-fourths of a number increased by one-half is equal to fourteen:

3/4 x + 1/2 = 14

Multiply both sides by 4

3x + 2 = 56

Subtract 2 from both sides

3x = 54

Divide both sides by 3

x = 18

Answer: The number is 18
