it should be written:
x^2-15x+36=0
(x )(x ) is the beginning way to write it to work it out. ignore that they look like boobies.
through diamond method, we find that -12 and -3 multiply together and get 36, yet add together to -15.
this gives us (x-12)(x-3). The roots should be easy to find here, using arithmetic.
x=12, or 3.
Hope this helps ^.^
The roots are: x = -5 and x = -9
This quadratic equation has no real roots because its discriminant is less than zero.
No. It is a quartic equation. The largest power of x in a quadratic equation must be 2.
NO,because in quadratic equation highest power of a variable is 2. e.x. 4x2-20x+10=0.
use the quadratic formula. when done so the roots are z=-3, and z=-6
The roots are: x = -5 and x = -9
This quadratic equation has no real roots because its discriminant is less than zero.
x = 2 and x = 4
Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913
If you mean b^2 -4ac then it is the discriminant of a quadratic equation. If the discriminant equals 0 then the equation has 2 equal roots. If the discriminant is greater than 0 then the equation has 2 different roots. If the discriminant is less than 0 then it has no real roots.
It is a quadratic equation in X, with two real roots.
Use the quadratic formula, with a = 1, b = -3, c = 2.
The discriminant is -27 and so there are no real roots.
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
No. It is a quartic equation. The largest power of x in a quadratic equation must be 2.
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
It is a quadratic equation with one unknown variable, x which has no real roots.
