a^2 - 2a - 24 = 0 6x^2 - x = 2 5x^2 - 11x - 3 = 2x - 3

Solution

Dear Student

Thank you for using Cehgg !!

a^2 - 2a - 24 =0

the equation can be solved by splitting the middle term into sum of -6 +4 which has a sum of -2 and product of -24 as required

a^2 -6a + 4a -24 = 0

a( a- 6) + 4 (a - 6) = 0

( a + 4) (a - 6) = 0

a = -4,6
