It is a polynomial expression in x. What about it?
Five plus five equals ten.
2x2-5 = 0 +5 +5 2x2 = 5 /2 /2 x2 = 5/2 sqrt(x2) = sqrt (5/2) x = sqrt(5/2) Ps: Sqrt means square root
Ten.Five plus five equals ten. Written in numbers, that is: 5+5=10
one hundred seventy-five million
five
-3/16 since the answer is negative (the second number is larger) and the problem is subtraction you minus the second number from the first then make the answer negative and you have the answer
-9 minus -5 is -4
1/25
-2 minus -5.5 is 3.5
-6
negative ten sevenths
-5.5 (negative five point five)
Five minus eleven is negative six, or 5-11=-6.
(x - 5)(x + 5)
-7 minus 5 is -12.
