Question

Solve each quadratic by using the wuadratic formula and round the answer to the nearest hundredth, if possible.

1. x^2 = 9

2. 0 = 3x^2 - 8

Answer 1

quadratic formula
x = (-b +- (sqrt(b^2 - 4ac)))/2a

1) x^2 = 9
x^2 - 9
a = 1, b = 0, c = -9

x = 0 +- (sqrt(0^2 - 4(1)(-9)))/2(1)
x = + - (sqrt(0 + 36))/2
x = +- (sqrt36)/2
x = +- 6/2
x = +- 3
x = 3, -3
you try number 2

Answer 2

8q2 – 3q – 2 = 0
