It is an equation and the value of x is 7/19
3x2 + 22x + 7 = 3x2 +21x + x + 7 = 3x(x + 7) + (x + 7) = (x + 7)(3x + 1)
-3x2 + 22x = 0 You start by dividing both sides by x: ∴ -3x + 22 = 0 Then rearrange to solve for x: ∴3x = 22 ∴ x = 7 + 1/3
(2, -1)
y = 3X - 1
y = 3x + 1
If: 3x+5 = 4x+1 Then: x = 4
It is a quadratic equation and the values of x are: -1/2 and 6
(1, 1)
x + 2 = 3x-1 -2x = -3x = 1,5
It is called the commutative property, a + b = b + a
1
0 because X= -1
