What is 25y squared minus 9?
25Y2 - 9 = 0 25Y2 = 9 Y2 = 9/25 take square root each side Y = sqrt(9/25) Y = 3/5 -----------------check 25(3/5)2 - 9 = 0 25(9/25) - 9 = 0 9 - 9 = 0 0 - 0 -------------checks
How do you do solve for y in 25times y squared-9 equals 0?
25y2 - 9 = 0Factor the expression on the left side of the equation:(5y + 3) (5y - 3) = 0The equation is a true statement if either factor is zero:5y + 3 = 05y = -3y = -3/5and5y - 3 = 05y = 3y = 3/5
What the prime factors of the trinomial 16x -40xy plus 25y?
I think that wants to be 16x2 - 40xy + 25y2 That factors to (4x - 5y)(4x - 5y) or (4x - 5y)2

How do you factor 25y2-36x2?
You can use the formula for the difference of two squares in this case. - In general, for factoring, check whether the expression to be factored corresponds to one of several common forms - as in this case.
Sketch the following 4x2 plus 25y2 equals 100?
4x2 + 25y2 = 100 (divide each element of both sides by 100) x2/25 + y2/4 = 1 This is the equation of an ellipse of the form x2/a2 + y2/b2 = 1, whose center is at (0, 0), a = 5, b = 2, and so c = √(a2 - b2) = √19) Since the major axis is horizontal and it lies on the x-axis, the vertices are 5 units to the left and 5 units to the right of the center (0, 0). Vertices are (-5, 0) and (5, 0). The minor axis is vertical and it lies on the y-axis, so the graph of the ellipse crosses the y-axis at the points (0, -2) and (0, 2), since b = 2) The foci are √19 units to the left and √19 units to the right of the center (0, 0). The foci are (-√19, 0) and (√19, 0).
How do you factor x squared minus 25 y squared?
This is a special kind of expression called a difference of squares. Anything in the format a2 - b2 can be factored out as (a + b)(a - b). So we can say: x2 - 25y2 = x2 - (5y)2 = (x + 5y)(x - 5y)
What is 25y to the second power minus 64?
(25y2 - 64) is the same thing as (5y + 8) times (5y - 8). That's only the factored form. It doesn't tell you how much the whole thing is equal to. That depends on the value of 'y', and it changes immediately any time 'y' changes.
Factor expression 16x2 - 25y2?
Remember both 16 & 25 are squared numbers. 16 = 4^2 & 25 = 5^2 Hence we can write (4x)^2 - (5y)^2 Remember two squared terms with a NEGATIVE Between them will factor. ( 4x - 5y)(4x + 5y) Note the difference signs. NNB Two squared terms with a positive (+) between them DOES NOT factor.
