Question

Alguém me ajude a responder!!!

Answer 1

a)

a=4

b=5

c=10

b)a=3

b=3

c=0

c)

a=2

b=0

c=-4

d)

a=2

b=10

c=3

e)

(x+3)² + (x-2)(x+2)=0

(x²+6x+9)+(x²-4)=0

2x²+6x+5=0

a=2

b=6

c=5

f)(2x+2)²-(x+5)(x-5)=(x-1)²

(4x²+8x+4x)-(x²-25)=(x²-2x+1)

3x²+8x-21=x²-2x+1

2x²+10x-22=0

a=2

b=10

c=-22

g)

x²+3x-10=0

a=1

b=3

c=-10
