1. Using the numbers 1-20, and only using a number once, fill in the blanks. There may be multiple correct answers a) (x + ___)(x + ___) = x2 + ___x +

b) (x + ___)(x + ___) = x2 + ___x +
2. Using the numbers 1-40, and only using a number once, fill in the blanks. There may be multiple correct answers

a) (___x + 2)(___x + 5) = x2 + +

b) (___x + 2)(___x + 5) = x2 + +

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
