Question

Please tolong jawab, cuma no 2 sampai 9 aja pleassssseeeeee yaaaa

Answer 1

Banyak amat sih 3 aja kale

Answer 2

2. x²+9x+20= x²+4x+5x+20
= x(x+4)+5(x+4)
= (x+5) (x+4).
3. x²+7x+12= x²+4x+3x+12
= x(x+4)+3(x+4)
= (x+3) (x+4).
4. p²-5p+4= p²-4p-p+4
= p(p-4)-1(p-4)
= (p-1) (p-4).
5. a²+8a+12= a²+2a+6a+12
= a(a+2)+6(a+2)
= (a+6) (a+2).
6. m²+8m+16= m²+4m+4m+16
= m(m+4)+4(m+4)
= (m+4) (m+4)= (m+4)².
7. p²-8p+12= p²-2p-6p+12
= p(p-2)-6(p-2)
= (p-6) (p-2).
8. b²+6b+9= b²+3b+3b+9
= b(b+3)+3(b+3)
= (b+3) (b+3) = (b+3)².
9. p²-4p+4= p²-2p-2p+4
= p(p-2)-2(p-2)
= (p-2) (p-2)= (p-2)².
