Question

Use the quadratic formula to solve this equation. 4x^2-7x+10=0

Answer 1

x=7±i√111

all to the right of the x divided by 8.

Explanation:

I did this in an assessment a bit ago.

Answer 2

No solution is there

Explanation:

• Use the quadratic formula. Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

• Simplify the solution.

1. Evaluate the exponent
2. Multiply the numbers
3. Subtract the numbers
4. Multiply the numbers

• No real solutions because the discriminant is negative. The square root of a negative number is not a real number
• d = (- 111)
