Answers
Answer:
1. x ²+ 5x + 6=0
x² +3x + 2x+6=0
x(x+3) +2(x+3)=0
(x+2)(x+3)=0
further
x= -2
x= -3
2. x²-10x+24
x² -6x-4x+24=0
x(x-6)-4(x-6)=0
(x-6)(x-4)=0
3.
y² +10y + 24=0
y² + 6y + 4y +24=0
y(y+6)+4(y+6)=0
(y+4)(y+6)=0
4. x² -23x+42=0
x ²- 21x- 2x +42= 0
x(x-21)-2(x-21)=0
(x-2)(x-21)=0
5. x²-17x+16=0
x²-16x-x+16=0
x(x-16)-1(x-16)=0
(x-1)(x-16)=0
6. x²-9x+20=0
x²-4x-5x+20=0
x(x-4)-5(x-4)=0
(x-4)(x-5)=0
7. y²+7y-144=0
y²+16x-9x-144=0
y(y+16)-9(y+16)=0
(y+16)(y-9)=0
8. z²-12z-45=0
z²-15x+3z-45=0
z(z-15)+3(z-15)=0
(z+3)(z-15)=0
9. x²-22x+117=0
x²-13x-9x+117=0
x(x-13)-9(x-13)=0
(x-9)(x-13)=0
10. p²-4p-77=0
p²-11p+7p-77=0
p(p-11)+7(p-11)=0
(p+7)(p-11)=0
11. x²-5x-104=0
x²-13x+8x-104=0
x(x-13)+8(x-13)=0
(x+8)(x-13)=0
12. x²-7x-30=0
x²-10x+3x-30=0
x(x-10)+3(x-10)=0
(x+3)(x-10)=0
13. z²+19z-150=0
z²+25x-6x-150=0
z(z+25)-6(z+25)=0
(z-6)(z+25)=0
