5.
2x2-5 = 0 +5 +5 2x2 = 5 /2 /2 x2 = 5/2 sqrt(x2) = sqrt (5/2) x = sqrt(5/2) Ps: Sqrt means square root
x=5
12x = 11x - 5, subtract both sides by 11x x = -5
x2 - 5x = 0Factor the left side:x (x - 5) = 0x = 0x = 5
5.
(x-5)(x+3)
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
(x - 3)(x + 5)
x = 25 / 3squared + 5
5x2=8x Divide with x on both sides5x= 8 Solve xx=8/5
Your Problem: X - 4 = ?Current Problem: 3 [squared] - 4 = ?How: When a numbered is squared, it means you multiply it against itself. So, 3 squared equals 3x3.3x3 = 9So, you would then take 9 and minus it by 4, which would than equal 5.Answer:3 [squared] - 4 = 5or9 - 4 = 5
25
Without mathematical notation it's hard to understand the question, but if your question is 5 times s-squared = 25 times s then "s" = "5".
It is: 9-4 = 5
a equals 5
to evaluate 5 squared you must simply do 5x5. Which equals 25.
