Simplify the linear expression. −2x+3(−5x+1) Enter your answer in the box.

Step-by-step explanation:

Simplify the linear expression. −2x+3(−5x+1) Enter your answer in the box.

−2x+3(−5x+1)

Step-by-step explanation:

The first step towards simplifying −2x+3(−5x+1) is to apply the Distributive Property of Multiplication.

−2x+3(−5x+1) becomes −2x - 15x + 3.

Next we combine the x-terms, obtaining -17x + 3

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
