Question

solve the equation no: 3,9,14,

Answer 1

hey friend
Q3. m²+13m+42
= m²+6m+7m+42
= m(m+6)+7(m+6)
= (m+6)(m+7)
Q9. x²-2x-24
= x²-6x+4x-24
=x(x-6)+4(x-6)
= (x-6)(x+4)
Q.14
c²-18c+65
=c²-13c-5c+65
= c(c-13)-5(c-13)
=(c-13)(c-5)
thank you

Answer 2

3. m^m+13m+42
= m^m +(7+6)m +42
= m^m +7m+6m+42
= m (m+7)+6 (m+7)
= (m+7)(m+6)

9. x^x-2x-24
= x^x-(6-4)x-24
= x^x-6x+4x-24
= x (x-6)+4 (x-6)
= (x-6) (x+4)

14. c^c-18c+65
= c^c-(13+5)c+65
= c^c-13c-15c+65
= c(c-13)-5 (c-13)
= (c-13) (c-5)
