Answer:
x = -2/3; x = 5/2.
Step-by-step explanation:
6x 2 - 11x - 10 = 0
Use the 'ac' method:
6 * -10 = -60. We need 2 numbers whose product is -60 and whose sum is -11.
That would be -15 and +4. So we write:
6x^2 - 15x + 4x - 10 = 0 Factor by grouping:
3x(2x - 5) + 2(2x - 5) = 0
(3x + 2)(2x - 5) = 0
x = -2/3; x = 5/2.

Answer:
2) x = 24
Step-by-step explanation:
-5/4x - 5 = -35
~Add 5 to both sides
-5/4x = -30
~Multiply 4/5 to both sides
x = 24
Best of Luck!
