Question

Kak tolong bantu dong kak soal matematika dan tolong dengan caranya kak plisss kak

Answer 1

1.)
(5x+3y-2)+(-x+y+3)
=5x+3y-2-x+y+3
=5x-x+3y+y-2+3
=4x+4y+1
2.)
(2p²+3q-4)+(5p²-3q+2)
=2p²+3q-4+5p²-3q+2
=2p²+5p²+3q-3q-4+2
=7p²-2
3.)
(7a²+2a-5)-(2a²-10a+3)
=7a²+2a-5-2a²+10a-3
=7a²-2a²+2a+10a-5-3
=5a²+12a-8
4.)
(3x+2)(x-1)
=3x²-3x+2x-2
=3x²-x-2
5.)
(5x²-45)
=5(x²-9)

maaf cuma itu yg tau
