The equation is a quadratic in x2, so using the quadratic formula:
x2 = [7 +/- √45]/2
so that x2 = 0.145898 or x2 = 6.854102
then x = √0.145898 = -0.381966 or +0.381966
or x = √6.854102 = -2.618034 or +2.618034
y = 6
A false statement.
X = 5
The discriminant is 900.
The discriminant is 609.
y = 6
A false statement.
X = 5
The discriminant is 900.
The discriminant is 609.
T = 6.0382422
The discriminant is 1.
The discriminant is 385.
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
Yes because if 1+0=1 than 0 plus b equals b
- 8x + 8x = 0 so question is meaningless.
