✔ 最佳答案
(x + 3)(x + 2)= x*x + 3*x + x*2 + 3*2
= x^2 + 3x + 2x + 6
= x^2 + 5x + 6

x² + 2x + 3x + 6
x² + 5x + 6
x² + 5x + 6

Using the foil technique....
x squared + 2x + 3x +5
X squared + 5x +5 = Answer
x squared + 2x + 3x +5
X squared + 5x +5 = Answer

(x + 3) (x + 2)
x² + 3x + 2x + 6
x² + 5x + 6
Method :
x times x = x²
3 times x = 3x
2 times x = 2x
3 times 2 = 6
So : (x + 3) (x + 2) = x² + 5x + 6
x² + 3x + 2x + 6
x² + 5x + 6
Method :
x times x = x²
3 times x = 3x
2 times x = 2x
3 times 2 = 6
So : (x + 3) (x + 2) = x² + 5x + 6
