Question

x² - 10x +16=0 ( by factoring) In mathematics​

Answer 1

Resposta:

S={8;2}

Explicação passo a passo:

x²-10x+16=0

a= 1   b= -10  c= 16

Δ= b²- 4·a·c

Δ=(-10)²-4.1.16

-10×-10=100   e     4×1×16=64

Δ=100-64

Δ=36

X= -b±√Δ/2.a

X= -(-10)±√36/2

X= 10±6/2

X1= 10+36/2= 16/2=8

X2= 10-6/2= 4/2=2
