Answer:
x= -24
Step-by-step explanation:
-1/4x-2/3x= -6+28
add -6 to 28 but since 6 is a negative its subtraction
-1/4x-2/3x=22
multiply all by 12
-3x-8x=264
add -3x to -8x
-11x=264
divide both sides by -11
x= -24
Answer:
How do you find the sum of factors of a quadratic equation?
Let r and s be the factors for the quadratic equation such that x^2+Bx+C=(x−r)(x−s) where sum of factors (r+s)=−B and the product of factors rs = C r = -2 - u s = -2 + u Two numbers r and s sum up to -4 exactly when the average of the two numbers is \frac{1}{2}*-4 = -2.
How do you solve a quadratic equation?
Quadratic equations such as this one can be solved by completing the square. In order to complete the square, the equation must first be in the form x^{2}+bx=c.
