What is 9x squared minus 16y squared factored?
This is a difference of two squares, which factorises to: (3x - 4y)(3x + 4y)
Factor 25x squared minus 4y squared?
(5x - 2y)(5x + 2y)
How do you solve this problem what is the value of the expression 2x squared plus 3xy - 4y squared when x equals 2 and Y equals 4?
x = 2 so x squared = 4 and 2x squared = 2 times 4 = 8; y = 4 so xy = 2 times 4 = 8 and 3xy = 3 times 8 = 24; y squared = 4 times 4 = 16 and 4y squared = 4 times 16 = 64; so 8 + 24 - 64 = 32 - 64 = -32
Simplify the algebraic expression 7x squared minus 4y plus 3x squared plus 5y plus 2 and evaluate it for x equals 3 and y equals 9?
7(3y-2)-(-4y+9)
What is the ordered pair for 2x plus 4y equals 16 and 2x-4y equals 0?
2x + 4y = 16 <=> 2x + 4y - 16 = 0 2x - 4y = 0 2x - 4y = 2x + 4y - 16 -8y = -16 y = 2 Substituting the known value for y in either of the original equations enables x to be determined. 2x + (4*2) = 16 : 2x = 16 - 8 : x2x = 8 : x = 4 2x - (4*2) = 0 : 2x - 8 = 0 : 2x = 8 : x = 4. The ordered pair satisfying both equations is (4,2)
What is xy minus 2x plus 4y minus 8?
(y-2) (x+4)
What is 2x minus 4 plus x minus 2 plus 4y?
This simplifies to 3x-6+4y.
What is 9x squared minus 16y squared factored?
This is a difference of two squares, which factorises to: (3x - 4y)(3x + 4y)
How do you solve a linear equality with two unknowns?
Isolate one of the variable using inverse operations. Then solve. Example: 2x + 4y = 0 --subtract 4y>> 2x = -4y --divide by -4>> -1/2x = y --plug in your variable -->>
Factor 25x squared minus 4y squared?
(5x - 2y)(5x + 2y)
What is the name of this function 4y plus 8 equal to 3x to the power of 2 minus 2x plus 1?
if you rearrange it, it becomes 4y + 8 = 3x2 -2x +1 4y = 3x2 -2x -7 y= (3x2 -2x -7)/4 which is a parabola
What is the y-intercept of 2x-4y equals -8?
2x-4y=-8-2x......-2x-4y=-2x-8(-4y)/-4 | (-2x-8)/-4y=1/2x+2
How do you solve -2x plus 4y equals 8?
You cannot solve one equation in two unknowns.
What is 3 2X equals 12 and 4Y minus X equals five?
If you mean: 3+2x = 12 and 4y-x = 5 then their values are x = 4.5 and y = 2.375
How do you factor 4y squared minus 36?
4(y - 3)(y + 3)
How do you factor 26x to the fourth - 73x squared y plus 20y squared?
(13x^2 - 4y)(2x^2 - 5y)
What is 4y squared minus 4 y minus 12?
it depends,if y = 0 the answer is -12 if y = 5 then the answer is 368
