84 = 2² 3 7
-Find two numbers that added gives 5
These numbers are 12 and -7
- Express the equation using these numbers
2x² + 12x - 7x - 42
-Factor by common factor
2x(x + 6) -7(x + 6)
-Factor by grouping
(x + 6)(2x - 7)
-Find the roots
x₁ + 6 = 0 2x₂ - 7 = 0
x₁ = -6 2x₂ = 7
x₂ = 7/2
Step-by-step explanation:
3x - 3x -y + 3y = 27-1
2y = 26
y = 13 use this to find the value of x
3x - 13 = -1
3x = -1 + 13
3x = 12
x = 4
