Question

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

Answer 1

x =(3-√41)/-8= 0.425
x =(3+√41)/-8=-1.175

Answer 2

The quadratic equation is -b +/- (square root(b^2 - 4ac))/2a
In the equation a=-4, b=-3, c=2
THerefore

-(-3) +/- square root ((-3)^2 - 4(-4)(2))/2(-4)
which equals
3 +/- square root (9- (-32))/-8
which equals
3 +/- square root(41)/-8
