Solve 2x^2- 7x - 4 = 0 using the Quadratic Formula.

The final answers are:

Step-by-step explanation:

-The equation:

Use the Quadratic Formula:

-Then, you solve:

-Multiply -7 by the exponent 2:

-Multiply to the 4 and the 2:

-Distribute -4 by 8:

-Add 49 and 32 together:

-Take the square root of 81:

-The opposite of -7 is 7:

-Multiply 2 times 2:

-Add both the 7 and 9:

-Divide 16 by 4 to get 4:

So, the first answer and you need to find the second answer.

-To find the second answer, you to reduce the fraction to lowest terms and canceling out the 2:

So, the second answer is .

-The results are:

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
