What are the coordinates of the roots of x2 plus 4x equals 0?
x2 + 4x = 0 ⇒ x(x + 4) = 0 ⇒ x = 0 or x = -4
Solve x2 plus 4x plus 3 equals 0?
x2 + 4x + 3 = 0 (x + 1)(x + 3) = 0 x ∈ {-3, -1}
What is the x-intercept of y equals -4x plus 4?
x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept
How do you factor x2 plus 4x equals 0?
x^2+4x=0 x(x+4)=0 x=0 and x+4=0 x=0 and x=-4
What is x2 plus 4x plus 4 equals 25?
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
Find the solutions for 4x squared plus 4x plus 1 equals 0?
x = -½
What are the coordinates of the roots of x2 plus 4x equals 0?
x2 + 4x = 0 ⇒ x(x + 4) = 0 ⇒ x = 0 or x = -4
Solve x2 plus 4x plus 3 equals 0?
x2 + 4x + 3 = 0 (x + 1)(x + 3) = 0 x ∈ {-3, -1}
What is the x-intercept of y equals -4x plus 4?
x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept
How do you factor x2 plus 4x equals 0?
x^2+4x=0 x(x+4)=0 x=0 and x+4=0 x=0 and x=-4
What is x2 plus 4x plus 4 equals 25?
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
What is the anwer to 4x plus 7 equals 9x plus 7?
4x+7=9x+7 -5x=0 x=0
What is the x-intercept in this eqution y equals -4x plus 4?
y = -4x + 4 x intercept is where y = 0 0 = -4x +4 4x = 4 x = 1
Factor this 4x plus 4 equals 0?
4(x + 1) = 0.
8 plus 4x-x equals 8?
8 + 4x - x = 8 3x = 8 - 8 x = 0
16x2 plus 8x plus 1 equals 0?
16x2 + 8x + 1 = 0 : This factorises to (4x + 1)(4x + 1) = 0 When 4x + 1 = 0 then 4x = -1 : x = -1/4.
