sederhanakan bentuk aljabar berikut 1.(x+5) (x-5). 2. (2a+ 6) (b-3). 3 (5a+5) (7b-7). 4 (6-x) (3x+1). 5.(x2-2) (x2+2).

1. (x + 5)(x – 5)
= x² -5x + 5x – 25
= x² – 25

2. (2a + 6)(b – 3)
= 2ab – 6a + 6b -18

3. (5a + 5)(7b – 7)
= 35ab – 35a + 35b – 35

4. (6 – x)(3x + 1)
= 18x + 6 – 3x – x

5. (x² – 2)(x² + 2)
= x⁴ + 2x² – 2x² – 4
= x⁴ – 4

Semoga Membantu

1.(x+5) (x-5) = x^ -5^

2. (2a+ 6) (b-3) = 2ab + -6a + 6b -18

3 (5a+5) (7b-7) = 35ab -35a +35b -35

4 (6-x) (3x+1) = 18X +6 – 3X^ -X = -3x^ +17x +6

5.(x2-2) (x2+2) = x4 + 2×2 -2×2 -4 = x4-4
