What is -x2 plus 6x plus 8?
4x+8
How do you solve x2 plus 4x equals 1?
x2 + 4x = 1 x2 + 4x - 1 = 0 in the quadratic formula (b2+- Sqr(4ac))/2a, a = 1 b = 4 c = -1 so x = 8 +- i
How do you factor x2 plus 4x-96?
x2 + 4x - 96 = (x - 8)(x + 12).
What is the factorization of x2 plus 4x - 32?
x2 + 4x - 32 = (x + 8)*(x - 4)
How do you factor x2 plus 4x - 32?
x2+4x-32 = (x-4)(x+8) when factored
What is -x2 plus 6x plus 8?
4x+8
How do you solve x2 plus 4x equals 1?
x2 + 4x = 1 x2 + 4x - 1 = 0 in the quadratic formula (b2+- Sqr(4ac))/2a, a = 1 b = 4 c = -1 so x = 8 +- i
What is X2-4x plus 9 when x equals -8?
If [ x = -8 ], thenx2 - 4x + 9= (-8)2 - 4(-8) + 9= 64 + 32 + 9= 105
How do you factor x2 plus 4x-96?
x2 + 4x - 96 = (x - 8)(x + 12).
What is the factorization of x2 plus 4x - 32?
x2 + 4x - 32 = (x + 8)*(x - 4)
How do you factor x2 plus 4x - 32?
x2+4x-32 = (x-4)(x+8) when factored
What is if any are the points of intersection of the parabolas y equals x2 -4x plus 8 and y equals 8x -x2 -14 showing work with explanations?
If: y = x2-4x+8 and y = 8x-x2-14 Then: x2-4x+8 = 8x-x2-14 So: 2x2-12x+22 = 0 Discriminant: 122-(4*2*22) = -32 Because the discriminant is less than 0 there is no actual contact between the given parabolas
What is the solution set for x2-4x equals 8?
x2 - 4x = 8 x2 - 4x + 4 = 8 + 4 (x - 2)2 = 12 x - 2 = +&- sq. root of 12 x = 2 +&- 2(sq. root of 3)
4x plus 32 equals -4x plus 16 x equals?
4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
What is the vertex of the parbola y equals x2-4x plus 12?
Y = X2 - 4X + 12 set to 0 X2 - 4X + 12 = 0 subtract 12 from each side X2 - 4X = - 12 now, take the linear term ( - 4 ), halve it, square it and add it to both sides X2 - 4X + 4 = - 12 + 4 factor the left side, gather terms on the right (X - 2)2 = - 8 add 8 to each side (X - 2)2 + 8 = 0 ------------------------ (2, 8) ------------the vertex of this function
What is 4x plus -12 equals 8?
If: 4x+(-12) = 8 then 4x = 20 and x = 5
X2 plus 2x - 14 equals 6?
X2 + 2X - 14 = 6X2 + 2X - 8 = 0what two products of - 8 = 2 ?(X +4)(X - 2)=========X = - 4X = 2
