The expression (5x^2 + 7x + 2) is a quadratic polynomial in standard form, where (5) is the coefficient of (x^2), (7) is the coefficient of (x), and (2) is the constant term. This polynomial can be used in various mathematical contexts, such as finding roots, graphing, or solving equations. To analyze it further, you could factor it or apply the quadratic formula if you need to find its roots.
5x2+ 7x + 2 = (x + 1)(5x + 2).
If you mean 5x^2 -7x +2 = 0 then it is a quadratic equation with solutions of x = 2/5 or x = 1
7x + 2
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
5x2+ 7x + 2 = (x + 1)(5x + 2).
When you subtract 7x^2 from 5x^2, you get -2x^2.
If you mean 5x^2 -7x +2 = 0 then it is a quadratic equation with solutions of x = 2/5 or x = 1
-12x-2Given: -5x-(7x+2)This is the same as -5x-1(7x+2). Use the distributive property and multiply the -1 through (7x+2).-5x-7x-2Simplify.-12x-2
((15xy2)/(x2+5x+6))/((5x2y)/(2x2+7x+3)) =(15xy2/5x2y)*(2x2+7x+3)/(x2+5x+6) =(3y/x)*(((2x+1)(x+3))/((x+2)(x+3) =(3y(2x+1))/(x(x+2)) =(6xy+3y)/(x2+2x)
7x + 2
7x + 12 = 5x + 2 Subtract '12' from both sides Hence 7x = 5x -10 Subtract '5x' from both sides. 2x = -10 Divide both sides by '2' Hence x = -5 .
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
5x-7x = -2
