98 points me with this, i have no clue what to do. but the only methods you have the option to use are these: isolate the variable, difference of squares perfect square trinomial, factoring, completing the square and quadratic formula

2x²=200

dividing both sides by 2

x²=100

x²-100=0

we can write 100 as 10²

x²-10²=0

using the property (a+b)(a-b)=a²-b²

(x+10)(x-10)=0

x+10=0, x=-10

x-10=0, x=10

x=+10 and x=-10

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
