x-2/3 = 0
x - 5/7 = 0
(x-2/3)(x-5/7) = 0
x^2 -2/3(x) -5/7(x) + 10/21 = 0
x^2 -14/21(x) - 15/21(x) +10/21 = 0
x^2 -29/21(x) +10/21 = 0
Another Answer:-
If: x = 2/3 and x = 5/7
Then: (3x-2)(7x-5) = 0
Multiplying out the brackets: 21x2-29x+10 = 0 which is the equation.
Check using the quadratic equation formula: x = 2/3 and x = 5/7

An equation whose solutions form a straight line on a coordinate plane?
A linear equation.
What are the roots of the equation x²-10x plus 25 equals 0?
Equations have 'solutions', not roots.Both of the solutions to this quadratic equation are x=5 .(The expression on the left side is a perfect square. So the graph of theexpression is a parabola whose nose rests on the x-axis at x=5, andboth x-intercepts are at the same point.)

How can you describe the graph of the equation ax plus by equals c?
ax + by = cThe graph if that equation is a straight line whose slope is (-a/b)and whose y-intercept is (c/b).
What statement must be true of an equation before you can use the quadratic formula to find the solutions?
The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.
