What are the solutions to the following polynomial equation:
x2 + 10x + 24 = 0
=> (x+6)(x+4) = 0
=> x = -6,-4
What are the solutions to the following polynomial equation:
x3 + 5x2 -14x = 0
=> x(x2+5x-14) = 0
=> x(x-2)(x+7) = 0
=> x =0, 2,-7
What are the solutions to the following polynomial equation:
x3 + x2 -25x-25 = 0
=> (x2-25)(x+1)
=> x= 5,-5-1
Solve using the quadratic formula:
m2 - 5m - 14=0
m = 7, m = -2
What are the solutions to the following polynomial equation:
x2 -3x - 54 = 0
=> (x-9)(x+6) = 0
=> x = 9,-6
What are the solutions to the following polynomial equation:
2x3 -10x2 -12x = 0
=> 2x(x2-5x-6) = 0
=> 2x(x-6)(x+1) = 0
=> x =0, 6,-1
What are the solutions to the following polynomial equation:
x3 + 6x2 -x -6 = 0
=> (x2-1)(x+6)
=> x= 1,-1,-6
Solve using the quadratic formula:
2x2 + 2x = 12
x = 2 , x = -3
What are the solutions to the following polynomial equation:
2x2 +5x - 3 = 0
=> (2x-1)(x+3) = 0
=> x = 1/2, -3
What are the solutions to the following polynomial equation:
x4 -11x2 +30 = 0
=> (x2-6)(x2-5)=0
=> x2=6 x2=5
=> x =sqrt 6, -sqrt6, sqrt 5,-sqrt5
What are the solutions to the following polynomial equation:
2x3 -3x2 -4x +6 = 0
=> (x2-2)(2x-3)
=> x= sqrt2,-sqrt2,3/2
Solve using the quadratic formula:
4b2 + 8b + 7 = 4
b = -1/2 , b = -3/2
What are the solutions to the following polynomial equation:
3x2 +8x +4 = 0
=> (3x+2)(x+2) = 0
=> x = -2/3, -2
What are the solutions to the following polynomial equation:
x4 -5x2 -36 = 0
=> (x2-9)(x2+4)=0
=> x2=9 x2=-4
=> x =3, -3, 2i,-2i
What are the solutions to the following polynomial equation:
x3 -5x2 +4x -20 = 0
=> (x2+4)(x-5)
=> x= 2i,-2i,5
Solve using the quadratic formula:
2x2 -36 = x
x = 9/2 , x = -4
