-- make a list of 20 or 30 small numbers
-- one at a time, put each number in place of 'y', and figure out what 'x' is
-- mark a point at the pair of numbers you have for (x, y) on the graph
-- after a while, you'll start to see the graph take shape, and you can fill in the gaps between the points

How would you factor 8x2 - xy - 7y2 The 2 after the x and y are the squares. so its 8x squared - xy - 7y squared.?
You can factor this multivariate polynomial (a polynomial with several variables, here x and y), by looking at it as a univariate polynomial in either x or y. This would give you a simple second order equation of the form ax2+bx+c, which you can solve. This will give you 2 solutions, say x1 and x2, and can then factor your polynomial to a(x-x1)(x-x2). In our case: a=8, b=-y and c=-7y2 and the solutions for this equation are x1=y and x2=-7/8*y and this gives us 8x2 - xy -7y2 = 8(x-y)(x+7/8y) = (x-y)(8x+7y)
What is the answer to 21y2 plus 72y-48 by factoring?
Step 1: 3(7y2 + 24y - 16) Step 2: 3(7y - 4)(y + 4) Assuming original expression was equal to zero, y = 4/7 or -4
What is the LCM of 7y2 x 49y8?
Since 98y9 is a multiple of 14y2, it is automatically the LCM of this problem.
How do you solve y4-84 plus 5y2?
You cannot solve it since only one side of an equation is given. If the equation was y4 + 5y2 - 84 = 0 then y4 + 12y2 - 7y2 - 84 = 0 or y2*(y2 + 12) - 7*(y2 + 12) = 0 or (y2 - 7)*(y2 + 12) = 0 then y2 = 7 or y2 = - 12 y = +or- sqrt(7) and, if you are in the complex domain, also y = +or- i*sqrt(12) where i is the imaginary square root of -1.
What is the result of isolating y2 in the equation below 9x2 plus 7y2 42?
To isolate ( y^2 ) in the equation ( 9x^2 + 7y^2 = 42 ), first subtract ( 9x^2 ) from both sides: ( 7y^2 = 42 - 9x^2 ). Then, divide both sides by 7: ( y^2 = \frac{42 - 9x^2}{7} ). Thus, the isolated form of ( y^2 ) is ( y^2 = 6 - \frac{9}{7}x^2 ).
How do you make a squared on a keyboard?
shift 6... 4^8 I just clicked the superscript button on the bold/italics/underline row and then typed the number and it worked. The superscript button is the one with the A squared symbol.
