How do you solve x squared plus 9 equals to zero?
The answer is x = 3i and x = -3i. {Where i= √(-1)}An expression in the form a2 - b2 can be factored into (a - b)(a + b), but you have a2 + b2 so this factors into (a - bi)(a + bi). Check by multiplying the binomials: a2 + abi - abi - (bi)2 the [abi]'s cancel, and i2 = -1, so you have a2 + abi - abi - -b2 which is a2 + b2, so it checks out. In this case, a is x and b is 3.

What is the difference between pre-defined formulas and user-generated formulas?
Pre-defined comes built in as a function. [=SUM(A1:A12] User-generated is created by the user. [=A1+A2]
What is the answer to a squared plus -5a squared - a squared - a?
a2 + -5a2 - a2 - a = a2 - 5a2 - a2 - a = a2 - 6a2 - a = -5a2 - a

What is the square root of a squared plus a squared equal?
sqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*asqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*asqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*asqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*a
Who were the people who first used fire to cook food?
cavemen? A2. The earliest is lost in the mists of time. From midden and fire remains, we can give an educated guess, but these have no guarantee of being the earliest.

What is the formula to calculate 149.99 minus 30 percent in Excel?
There are lots of ways of taking 30% of 149.99 away from 149.99. It is also the equivalent of getting 70% of it. Assuming the 149.99 is in cell A2, then any of these formulas will do it: =A2 - A2 * 30% =A2 - A2 * 0.3 =A2 * 70% =A2 * 0.7
