This question is incomplete. 2x2 + 3x - 100 can not be solved unless you tell us what it is equal to.
10-2 = 1 / 102 = 1/100
100 squared (100 x 100) = 10,000
-25
That's going to depend on the value of 'x'. But no matter what 'x' is, (x2-100) will be equal to the product of (ten more than 'x') and (ten less than 'x').
5x^2(4x - 5)(5x + 11)
They touch each other at (0, 100) on the x and y axis.
An algebraic expression
It is: 2.4+100+100 = 202.4
60 plus 9 plus 100 minus 100 equals 69,see 60 + 9 = 69, 69 + 100 = 169 - 100 = 69 and that is the awnser to 60 plus 9 plus 100 minus 100.

It is 16x squared plus 80x plus 100.Very complicated!
It might be possible to work this in your head. Your 98 is 100 minus 2. This means 98 plus 98 is 100 plus 100 minus 2 minus 2. That's 200 minus 4 which gives 196 as the answer.
If the 64 has a minus sign, then the solution is x = +/-5 Simplifying gives 4x squared = 100 ie x squared = 25...
102 or 100
109 = 9 + 100
3,000 plus 596 divided by minus 100 is equal to 2,994.04
