I always prefer quadratic formula as compared to factoring or completing the square to solve a quadratic equation.
"A quadratic equation is an algebraic equation of the second degree in 'x'. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a' and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term."
In order to solve a quadratic equation, I always prefer quadratic formula as compared to the other methods.
In many cases, a quadratic equation can not be converted into a square or into factors.
Therefore, quadratic formula is the only method to solve all type of quadratic equation.

I prefer solving quadratic equations with the quadratic formula. The formula is great for solving any equations like ones that factoring can’t. It is also easy to memorize and type in and check with a calculator.
Answer:
The sum of seven and five is 12 so the number would be 4 because 12 times 4 is 48 so the answer is "4" please give me brainliest!!
multi-step equations
Answer:
y = 2
Step-by-step explanation:
This equation can be solved three steps, classifying it as a multi-step equation.
To solve, you need to get the constants on one side and the variables on the other and then isolate the variable. These steps are illustrated below.
3y + 2 = 2y + 4 Subtract 2y from both sides of the equation.
y + 2 = 4 Subtract 2 from both sides of the equation.
y = 2

that Annabella selects a purple card?
A 7/37 B 7/30 C 7/23 D 23/30
Answer:
B 7/30
Step-by-step explanation:
P (Purple) = 70 / 300 = 7/ 30
Answer:
B
Step-by-step explanation:
Purple-70/300=7/30
Across the street the clock above city hall chimes every 30 minutes. Both the school bell
and the clock ring at noon. When will both bells ring again at the same time? Use Prime Factorization
Hello.
The answer is:
First find Lcm of 40 and 30 that is 120 (2*2*2*3*5)
the convert 120 by divinding by 30 = 120/30=4
So that means 2 hours later (2 hours after 12) so the answer is 2 pm
Have a nice day
