Solve 2x2 – 3x = 12 using the quadratic formula.
icang [17]

Quadratic Formula: (-b +/- sqrt(b^2 - 4ac)) / 2a

2x^2 - 3x = 12

2x^2 - 3x - 12 = 0

a = 2

b = -3

c = -12

(--3 +/- sqrt( (-3)^2 - 4(2)(-12) )) / 2(2)

3 +/- sqrt( 9 + 96 ) / 4

3 +/- sqrt(105) / 4

Answers: \frac{3 + \sqrt{105} }{4}, \frac{3 - \sqrt{105} }{4}

Hope this helps!

What is the measure of an exterior angle of a regular 7-sided polygon? The answer must be a decimal.
ale4655 [162]
1 interior angle = [(n-2)180]÷n
= [(7-2)×180]÷7
= 900÷7 = 128.57 °
an exterior angle = 180 - interior
= 180-128.57
= 51.43°
