It cannot be factored because the discriminant is less than zero.
Do you mean x2+11x-60 then if so it is (x-4)(x+15)
6x2 + 11x - 10 = (6x2 + 15x) - (4x + 10) = 3x(2x + 5) - 2(2x + 5) = (3x - 2)(2x + 5). Note, first, that the three co-efficients of the original quadratic expression are 6, 11, and -10. We need two numbers whose sum is 11 and whose product is (6)(-10) = -60. These two numbers turn out to be 15 and -4. Thus, we replace the middle term, 11x with 15x - 4x and proceed with the factorisation in the usual way.
4507 5267 - 500 - 200 - 60 = 4507
Thirty plus thiry
x = 10
60 - 20 = 20 + 20=============
6 + 11x - 60 =6 - 60 + 11x = -54 + 11x = 11x -54
-2(x + 5)(x - 6)
(x + 15)(x - 4)

60+60+60+60+60+60+60+60 =480 All the addition can happen in the same step. This is the same as 60*8.

It is: x2-16x+60 = (x-6)(x-10) when factored
60 + 60 + 60 + 50 + 50 + 40 + 30 = 350
-30 plus 60 = 30
The result of the equation - 130 plus 80 plus 60 plus 60, is found as follows;130 + 80 + 60 + 60= ( 130 + 80 ) + 60 + 60= 210 + ( 60 + 60 )= 210 + 120= 330Answer = 330
