3X - 23 + 4X + 6 = 5X + 8combining like terms, 7X - 17 = 5X + 8subtracting 5X and adding 17 to each side, 7X - 5X = 8 + 17Then, 2X = 25X = 12.5
5x-4y=8
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
if the x in "7x2" is variable x, then 7x(2)-5x=0 14x-5x=0 9x=0 x=0 if the x in "7x2" is a symbol for multiplication, then 7(2)-5x=0 14-5x=0 -5x= -14 5x=14 x= 14/5 x= 2 4/5 or, to factor it out... x(14-5)=0 x(9)=0 9x=0
It is a quadratic polynomial.
7x2 - 5x + 4 is not a monomial because it has more than one term. It is a quadratic polynomial.
14x2-7x2-16 7x2-16 (this can't be simplified any more)
2x+5x-24 7x2-24
The term with the highest power(s) of the unknown variable(s) is 7x2. The power is 2 so the expression is a binomial.
Either: (7x + 4)(x + 4) = 7x2 + 32x + 16 or: (7x - 4)(x - 4) = 7x2 - 32x + 16
That is not solvable. It's like saying 7x2=2x2
Since there is nothing following, none of them!
5x-19 = 16 5x = 16+19 5x = 35 x = 7
7x2 -4x -5x2 +2x = 2x2 -2x
25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
