2(2x + 5)(2x - 5)
2x(1-5)
-3
(2x+5)(2x+1)
x(2x + 5)
2x+y=1
2x+3y-5=0
2x+12-3x = 5 2x-3x = 5-12 x = -7
2x2 + 5x = x*(2x + 5)
y = 2x+5 whereas 2 is the slope and 5 is the intercept
Simplifying 4x + -5 = 2x + 7 Reorder the terms: -5 + 4x = 2x + 7 Solving -5 + 4x = 7 + 2x Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. -5 + 4x + -2x = 7 + 2x + -2x Combine like terms: 4x + -2x = 2x -5 + 2x = 7 + 2x + -2x Combine like terms: 2x + -2x = 0 -5 + 2x = 7 + 0 -5 + 2x = 7 Add '5' to each side of the equation. -5 + 5 + 2x = 7 + 5 Combine like terms: -5 + 5 = 0 0 + 2x = 7 + 5 2x = 7 + 5 Combine like terms: 7 + 5 = 12 2x = 12 Divide each side by '2'. x = 6 (your answer)
0 = -2x + 5y - 15 -5y = -2x - 15 y = 2x/5 + 3
