ax2 + bx + c = 0
Given
ax2 + bx = −c
Subtract c from both sides of the equation

Divide both sides of the equation by a

Complete the square and add to both sides

Square on the right side of the equation

Find a common denominator on the right side of the equation

Add the fractions together on the right side of the equation

?

Rewrite the perfect square trinomial as a binomial squared on the left side of the equation
Take the square root of both sides of the equation
Multiply both sides of the equation by 2
Square the left side of the equation

see the procedure

Step-by-step explanation:

we have

----> given

step 1

Subtract c from both sides of the equation

step 2

Factor the leading coefficient a

step 3

Complete the square and add to both sides

step 4

Divide both sides of the equation by a

step 5

Find a common denominator on the right side of the equation  and adds the fractions together on the right side of the equation

step 6

Rewrite the perfect square trinomial as a binomial squared on the left side of the equation

step 7

Take the square root of both sides of the equation

step 8

Subtract both sides of the equation by the term b/2a

step 9

Rewrite the final expression

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
