y = 2, 4, 6, 8
4x2-4x-3=0 can be written as (2x-3)(2x+1)=0 Anything times by 0 equals 0 ( the zero property of multiplication) therefore we need to make each one of these terms in brackets equal to 0. so 2x-3=0 giving x=3/2 and 2x+1=0 giving x=-1/2
If that's - 8x - 5, the answer is (2x + 1)(2x - 5). If that's + 8x + 5, it gets ugly in a hurry.
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
3(2x + 3y)(2x - 3y)
Squared numbers are just the number times itself. If it's a prime square, like 9, the factors are 3 x 3. If it's a composite square, like 16, the factors can be broken down further, from 4 x 4 to 2 x 2 x 2 x 2.
The [ 2x + 1 ] represents a function of 'y' .
The function rule for this is (1) it is a variable or phantom any letter that stands on its own is a phantom here is a example =Y(2x + 2x)=2=2=4x + Y=5 (I am a grade 8 i know how you feel)
3
Which means 0 = -1!
y = x2 + 2x + 1zeros are:0 = x2 + 2x + 10 = (x + 1)(x + 1)0 = (x + 1)2x = -1So that the graph of the function y = x + 2x + 1 touches the x-axis at x = -1.
2x - 1 = 0 2x = 1 x = 0.5
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
No. That is an equation. A fraction can be plugged into it for x or y. An example of a fraction is 1/2
Y = 2x + 1
No they are parallel.
-2x plus 3y equals 1
NM equals 2x + 1, as stated in the question!
