Solution
4(2+2+3)
Answer:
You can solve 4x2−8x−12=0 by first, dividing both sides by 4 . This will give x2−2x−3=0 .
From here, you can add 4 to both sides to get x2−2x+1=4 .
Now, factor both sides, giving (x−1)2=(2)2 .
Taking the Square Root, we get x−1=±2 .
Adding 1 to both sides, we get x=1±2 .
Therefore, the solution to this Quadratic is that x is equal to either −1 or 3 .
Testing the first value, we get:
4(−1)2−8(−1)−124+8−120=0=0=0
Testing the second value, we get:
4(3)2−8(3)−1236−24−120=0=0=0
Since both of these statements are true, we have confirmed that x=−1 , and x=3 are the solutions to this Quadratic Equation.
