The first step in solving quadratic equations by finding square roots is; C:square root both sides to isolate x
<h3>How to solve quadratic equations?</h3>
To answer this question, we will take an example of a quadratic equation that we need to find the square root as;
x² = 36
Now, to get the roots which are the values of x, we will first have to take the square root of both sides to Isolate x. Thus;
√x² = √36
x = ±6

Answer:
2
Step-by-step explanation:
If you divide 0 by any number you will get 0
If you will substitute x for 2 you will have:
2-2/2+2=0/4=0
Let's solve for x first,
3x + 5y - 5y = 1 - 5y
3x/3 = 1/3 - 5y/3
x = 1/3 - 5/3y
Let's now plug that into the other equation,
7(1/3 - 5/3y) + 4y = -13
7/3 - 35/3y + 4y = -13
7/3 - 7 2/3y - 7/3 = -13 - 7/3
- 7 2/3y (-3/23) = -15 1/3 (-3/23)
y = 2
The answer is 2
Answer:
This is an example of distribution
Step-by-step explanation:
The reason why is because the equation is linear and if you exclud the y it show that it can distribute.
Answer:
Combine like terms.
Step-by-step explanation:
3x+2y=16
