First you need to solve for y. So write 4x2+y=16 so y=16-4x2 Now write f(x)=16-4x2
The first equality is: x2 - 5 = -4x2 which gives 5x2 - 5 = 0 which is equivalent to x2 - 5 = 0 The second equality is: -4x2 = 3x which gives 4x2 + 3x = 0 The two results are inconsistent.
4x2 - 2x = 0
4x2 plus 3=11
(2x - 3)*(4x2 + 6x + 9) = 0
y=4x2+3x+8
x3 + 4x2 - 25x - 100 = 0
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
4x2-30 = 34 4x2 = 34+30 4x2 = 64 x2 = 16 x = 4
4x2-11X=7 ARRANGE IN STANDARD FORM
yes
Fraction: 16/2 equation, 4x2
