(a - 1)(a - 1)(a^2 + a + 1)(a ^2 + a + 1)

Solve the following equation for A : 2A/3 = 8 + 4A

Since you know the values of the two variables, a and y, plug it into the expression like this: 2a3 - 3ay = 6a - 3ay = 6(-1) -3(-1)(2) = -6 -3(-2) =-6 + 6 = 0

All you can factor out is the common factor 2. 2(a^3 - 64)

In rationalising quadratics 2a3 - 5a2 - 39 is an irrelevance. It is not a quadratic but a cubic and so not within the defined scope.

(2a3)(10a5)/4a1

2a3-16a2+30a Factor out 2a: 2a(a2-8a+15) (2a)(a-5)(a-3) This is the most factored form of this expression.

The answer is 30 moles.

5/5 equals one; the denominator decides how many equal pieces of the whole will constitute the whole. The answer is 2 1/2. 2 1/2 equals 2.5, and 2/5 equals .4. 2 1/2 times 2/5 equals 1. Or, 2.5 times .4 equals 1. Another way to look at it is this. The numerator of 2/5 is 2. What do I have to multiply the fraction 2/5 by in order to make the numerator equal to 5? The answer is 2.5; 2.5 times 2 equals 5. Another way: a fraction times its reciprocal equals 1. 2/5 has the reciprocal 5/2. [5/2 equals 2 and 1/2]. 2/5 times 5/2 equals 10/10, which equals 1.

Well, now isn't 2 plus 2 equals 42 times 2 equals 42 times 2 equals 2 plus 2 equals 42 times -2 equals 2 plus -2 equals 0 WAIT 2 times -2 equals negative 4 according to mathematics. No teacher nor professor has been able to even do more than stutter explaining this.3 times 3 equals 93 times -3 equals -9So why is the digit 2 different?

If 6a divided by 2 equals 12 then A equals

You use Plus as a symbol in Maths. Example, 2 Plus 2 equals 4. Or in symbols it would be 2+2=4. __________________________ Plus = + Equals = = (Equals equals =)

No.

no it equals 20, yes it equals 2 you illiterate piece of sh*t

0.5 times 2 equals 1.

that equals 2*2*2 which equals eight

no if 1 plus 1 equals 2 then 2 plus 2 equals 4.

It equals two.
