X2 - 10X + 25 = 0
This is factorable, (X - 5)2, but you asked for this,
X = - b (+/-) sqrt(b2 - 4ac)/2a
a = 1
b = - 10
c = 25
X = - (- 10) (+/-) sqrt[(- 10)2 - 4(1)(25)]/2(1)
X = 10 (+/-) sqrt(100 - 100)/2
X = 10/2
X = 5

a2+30a+56=0 , solve for a Using the quadratic formula, you will find that: a=-2 , a=-28
By using the quadratic equation formula
By using the quadratic equation formula: x = -5 and x = 3
For any quadratic ax2 + bx + c = 0 we can find x by using the quadratic formulae: the quadratic formula is... [-b +- sqrt(b2 - 4(a)(c)) ] / 2a
-34
2x2-10+7 = 0 Solving the quadratic equation using the quadratic formula will give you two solutions and they are: x = (5 - the square root of 11)/2 or x = (5 + the square root of 11)/2
x = 7/2 and also x = -3/2 by using the quadratic equation formula.
Using the quadratic equation formula: x = 8.42 or x = -1.42
