1. Determine the solutions to the following by factoring. x^2 - 10x + 21 = 0 *

1 point

x = 7, -3

x = -7, -3

x = -7, 3

x = 7, 3

2. Determine the solutions to the following by factoring. 2x^2 -8x - 24 = 0 *

1 point

x = 2, -6

x = -2, 6

x = -2, -6

x = 2, 6

3. Determine the solutions to the following by factoring. 11x^2 = x^2 + 8x. Remember you must move everything to the left side of the equal sign(you opposite signs to move terms and combine like terms only) and set it equal to zero to get it in standard form. 11x^2 = x^2 + 8x *

1 point

x = 0, 0

x = 0, 8

x = 0, .8

x = 0, 1

4. Determine the solutions to the following by factoring. x^2+12x=x-24. Remember you must move everything to the left side of the equal sign(you opposite signs to move terms and combine like terms only) and set it equal to zero to get it in standard form x^2+12x=x-24 *

1 point

x = 3, 8

x = -3, 8

x = 3, -8

x = -3, -8
