Question

1.(3x-4)(2x+3)
2.(3y-1)(y+2)
3.(x+5)(x-3)


mohon bantuannya dong!

Answer 1

1) 6x+9x-8x-12= 7x-12
2)3ykuadrat+6y-y-2= 3ykuadrat+5y-2
3)xkuadrat-3x+5x-15= 3xkuadrat+2x-15

Answer 2

1. (3x - 4)(2x + 3)
= (3x × 2x) + (3×3x) +(-4×2x) +(-4×3)
= 6x² + x - 12

2. (3y-1)(y+2)
= (3y×y) + (3y×2) + (-1×y) + (-1×2)
=  3y² +5y - 2

3. (x+5)(x-3)
= (x×x) + (-3×x) + (5 × x) +(-3×5)
= x² + 2x - 15
