9x2-9x-10 = (3x+2)(3x-5) when factored
(3x - 1)(2x - 7)
The expression simplifies to: -7x-4
It is possible.
"sum" is not the right word here. All the bits are not being added: there is an equals sign. But 9x plus 14x can only be 23x, so that 23x + 8 = 0. Take 8 from each side of the equality so 23x = -8, and then divide both sides by 23 to get x = -8/23 Don't confuse"x" with the multiplication sign. For that reason, in algebra, a curly x is used wherever possible.
(9x - 8)(5x + 7)
9x2-9x-10 = (3x+2)(3x-5) when factored
5x2 + 9x + 13 has no real factors.
(3x - 1)(2x - 7)
If you mean (9x-8y)(9x+8y) then it is 81x^2 minus 64y^2
The expression simplifies to: -7x-4

32 minus the product of 9 and a number is 140 the answer is 12. 32-9x=140 9x=108 x=12
(9x + 8)(9x - 8)
With the help of the quadratic equation formula
x2-9x can be factored by taking x out of each term x(x-9)
