5x to the seventh
25x2+30x+9 25*9=225 15*15=225 15+15=3025x2+15x+15x+9[5*5xx 3*5x] [3*5x 3*3]5x(5x+3)+3(5x+3)(5x+3)(5x+3)Answer: (5x+3)2
5x-5 = -3 5x = -3+5 5x = 2 x = 2/5
5x+3 = -17 5x = -17-3 5x = -20 x = -4
5x² - 18x + 9 = (5x² - 15x) - (3x - 9) = 5x(x - 3) - 3(x - 3) = (5x - 3)(x - 3).
(x - 3)(5x + 1)
If you mean (5x+3)2 = 36... 5x+3 must equal 6 so - 5x has to equal 3 - therefore x = 0.6
3 - 5x - 2x = 3 - 7x( 3 - 7x )2 = 9 - 42x + 49x2
x2-5x = 24 x2-5x-24 = 0 (x-8)(x+3) = 0 x = 8 or x -3
5x to the seventh
The square root of anything to an even power is that thing to half the power. √(5x^13) = √(x^12 5x) = √(x^12) √(5x) = x^6 √(5x) But is that really any simpler?
5x^3(3x + 2)
5x-3 would be the answer.
3 + 5x is the simplest expression of this problem.
5x plus 3 does equal 3 plus 5x; commutative law.
