Question

Use the quadratic formula to solve the equation.
–4x^2 – 3x + 2 = 0

Answer 1

Compare your quadratic equation with \(ax^2+bx+c=0\)
find a,b,c
then the two roots of x are:
\(\huge{x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}}\)

Answer 2

Here,
a=-4
b=-3
c=2

therefore,\[\LARGE{-(-3) \pm \sqrt{(-3)^2-4(-4)(2)}\over2(-4)}\]

Answer 3

solve this :)

Answer 4

Adding on to hartnn's equation, a=-4, b=-3 & c=2 .

Answer 5

So just plug and solve

Answer 6

Adding on to hartnn's equation, a=-4, b=-3 & c=2 .
