Question

Which of the following options best describes the solution process and solution(s) for the quadratic equation?

-2x2 + 3x + 4 = 7



1.factoring; two real rational number solutions
2.quadratic formula; two non-real rational solutions
3.factoring or quadratic formula; two real irrational number solutions
4.quadratic formula or completing the square; two real irrational number solutions

Answer 1

Option c)

Explanation:

Given quadratic equation is

`-2x^2+3x+4=7`

`-2x^2+3x+4-7=0`

`-2x^2+3x-3=0`

Multiply the above equation into (-) we get,

`2x^2-3x+3=0`

To find the solution of quadratic equation
`ax^2+bx+c=0` is
