Answer:
Step-by-step explanation:
(x²+4)²-11(x²+4)+24=0
put x²+4=y
y²-11y+24=0
y²-3y-8y+24=0
y(y-3)-8(y-3)=0
(y-3)(y-8)=0
y=3,8
so x²+4=3
x²=-1=i²
x=±i
or x²+4=8
x²=4
x=±2
kookooo
She didn't wasn't supposed to subtract 57, she was suppose to add.
x=2
a=19
2x+3=7
2x+3-3=7-3
2x=4
2x/2=4/2
418=-22a
418/(-22)=-22a/(-22)
19=a
