Use the quadratic formula to determine the exacty solutions of each quadratic equation. Then approximate each solution to the nearest hundredth.
y^2 - 5 = 0
y^2 = 5
y = +/-
That is:
y ~ +/- 2.24
:
5w^2 = 2w + 1
5w^2 - 2w - 1 = 0
The quadratic formula
In this problem x - w; a=5; b=-2; c=-1
:
:
;
Two solutions
w =
w ~ .69
And
w =
w ~ -.29
