Quadratic equations that can be solved using the quadratic formula can also be solved by factoring. ...?

1 answer:

5 0

I believe the correct answer is false. Quadratic equations that can be solved using the quadratic formula cannot always be solved by factoring. Not all quadratic equations can be solved by factoring. Another method that can be used is completing the square. Hope this answers the question.

Solving Exponential Equations (lacking a common base) 4^x-5=8

avanturin [10]

Answer:

x= 6 1/2 or 6.5

Step-by-step explanation:

4^x-5 =8

2^2(x-5) =2^3

since the base is equal, the powers are equal

2(x-5) = 3

2x - 10 = 3

2x = 3 + 10

2x = 13

2x/2 = 13/2

x = 6 1/2 or 6.5

Graph the solution to this inequality on the number line.

Svetach [21]

Given the inequality expression:

w−0.8>−2.4

Inequalities are expressions separated by an unequal sign.

According to the given question, we need to find the solution for "w"

w−0.8>−2.4

Add 0.8 to both sides

w−0.8+0.8>−2.4 + 0.8

w > -2.4 + 0.8

Simplify the result by adding to have:

w > -1.6

Find the number line representing the solution attached;
