Answer:
Step-by-step explanation:
Here are the steps required to solve a quadratic using the quadratic formula:
Example 1 – Solve: x²-8x+14=0
Step 1: Identify a, b, and c and plug them into the quadratic formula. In this case a = 1, b = –8, and c = 14.
Step 2: Use the order of operations to simplify the quadratic formula.
Step 3: Simplify the radical, if you can. In this case you can simply the radical into:
Step 4: Reduce the problem, if you can. In this case you can reduce the entire problem by 2.
x. 6
------. ------
14-x. 15
15(x) = 6( 14-x )
15x= 84-6x
15x + 6x = 21x
84 ÷ 21 = 4
x = 4
Answer:
u=50
Step-by-step explanation:
the angles of a triangle must add up to 180 degrees so set up the equation:
180=(u+48)+(u-14)+(u-4)
180=3u+30
150=3u
u=50
