1.	please solve this it's hard can you solve it and no funny answers the question is (x+a)(x–b) =x2+(a–b)x–ab
Answer» Answer: see Step-by-step explanation: x + a)(x + B) = (x + a)(x + b) = x^{2} + (a + b)x + ab for a = 2, b = 3 and x = 4. (4 + 2)(4 + 3) = (4)2+ ( 2 + 3 ) 4 + 2x3 6 x 7= 16 + 20+ 6 42= 42

Answer: see

Step-by-step explanation: x + a)(x + B) = (x + a)(x + b) = x^{2} + (a + b)x + ab for a = 2, b = 3 and x = 4.

(4 + 2)(4 + 3) = (4)2+ ( 2 + 3 ) 4 + 2x3

6 x 7= 16 + 20+ 6
