por favor ajudem​

Answer 1

5x²- 720 = 0

5x²= 720 muda o sinal

5x²= 5√720

x= √144

x= +- 12

Answer 2

Resposta:

5x²- 720 = 0

5x²= 720 muda o sinal

5x²= 5√720

x= √144

x= +- 12

Explicação passo-a-passo:

5x²- 720 = 0

5x²= 720 muda o sinal

5x²= 5√720

x= √144

x= +- 125x²- 720 = 0

5x²= 720 muda o sinal

5x²= 5√720

x= √144

x= +- 125x²- 720 = 0

5x²= 720 muda o sinal

5x²= 5√720

x= √144

x= +- 125x²- 720 = 0

5x²= 720 muda o sinal

5x²= 5√720

x= √144

x= +- 125x²- 720 = 0

5x²= 720 muda o sinal

5x²= 5√720

x= √144

x= +- 125x²- 720 = 0

5x²= 720 muda o sinal

5x²= 5√720

x= √144

x= +- 125x²- 720 = 0

5x²= 720 muda o sinal

5x²= 5√720
