5x3=15 is the inverse
2(10x6) 4(5x3)
What is the additive inverse of the polynomial –9xy2 + 6x2y – 5x3?
An expression. It can be factored out slightly too: 2x6 + 5x3 - 7x4 = x3(2x3 - 7x + 5)
5x3
5x3=15 is the inverse
The generalisation is that multiplication is Abelian (or commutative) for numbers.
1x15 3x5 5x3 15x1
All of them. 1x15,2x7.5, 3x5, 4x3.75, 5x3...
since 15 = 3x5 and 75 = 3x5x5 H.C.F = 5X3 = 15 !
5.3
2(10x6) 4(5x3)
seventeen over fifteen because the common denominator of 5 and 3 is 15 think about it like this: 4/5x3, 4x3=12, 5x3=15 1/3x5, 1x5=5, 3x5=15 so you get 12/15+5/15 see how they simplify back? then add the numerators and keep the denominator and you get 17/15 or 1 and 2/15
If you're asking what x equals, it equals 5 because 5x3=15, and 15-2=13.
3/5 - 1/3 = (3x3)/(5x3) - (1x5)/(3x5) = 9/15 - 5/15 = 4/15
5x3 = 45x Divide both sides by 5: x3 = 9x Divide both sides by x: x2 = 9 Square root both sides: x = 3
Since 5x is a factor of both terms, divide it. 5x3 + 5x = 5x(x2 + 1)
