Answer:
x= -3
Step-by-step explanation:
mark branliest pls
Standard form:
2×2 − 18 = 0
Factorization:
2(x + 3)(x − 3) = 0
Solutions based on factorization:
x + 3 = 0 ⇒ x1 = −3
x − 3 = 0 ⇒ x2 = 3
Extrema:
Min = (0, −18)
Answer:
x = ± 3
Step-by-step explanation:
Given
2x² – 5 = 13 ( add 5 to both sides )
2x² = 18 ( divide both sides by 2 )
x² = 9 ( take the square root of both sides )
x = ± [tex]\sqrt{9}[/tex] = ± 3
smaller solution is x = – 3
larger solution is x = 3
