Assume two lines do not coincide (~q). Then, either their slopes are different or their y-intercepts are different (~p). Since ~

q → ~p is true, p → q must be true. Therefore, if the slopes and y-intercepts are the same, then two lines coincide.

Rewrite the equation by completing the square.<br> 4x^2 + 28x + 49=0
Evgen [1.6K]

Answer:

4(x+3.5)^{2}=0

Step-by-step explanation:

we have

4x^{2}+28x+49=0

step 1

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(4x^{2}+28x)=-49

step 2

Factor the leading coefficient

4(x^{2}+7x)=-49

step 3

Complete the square. Remember to balance the equation by adding the same constants to each side

4(x^{2}+7x+3.5^2)=-49+(3.5^2)(4)

4(x^{2}+7x+12.25)=0

step 4

Rewrite as perfect squares

4(x+3.5)^{2}=0
