2x2 - 20x - 106 = 0
(20 +/- sqrt(400 + 848))/4
=(20 +/- sqrt 1248)/4
= (20 +/- 35.33)/4
= 55.33/4 or -15.33/4
= 13.83 or -3.83

What is x2 plus 7x equals - 2x2 plus 6 in the form ax2 bx c equals 0?
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
X2 plus 20x plus 4 equals 0?
x2 + 20x + 4 = 0 x2 + 20x + 100 = 96 (x + 10)2 = 96 x + 10 = ±961/2 x = -10 ±961/2 x = -10 ±4√6
What are number factors in maths?
4 equals 2x2, 6 equals 2x3
How do I solve this 2x3-3x2-20x-21 equals 0?
Set all numbers and variables equal to zero. (2x3)-(3x2)-(20x)-21=0 Next, follow the order of p.e.m.d.a.s. 6-6-20x-21=0 -20x-21=0 Separate the numbers and variables -20x=21 x= -21/20
Solution set for 4x2-6 equals 2x2?
Reading this as: 4x2-6=2x2 This implies that: -6=-2x2 3=x2 x=sqrt(3) and x=-sqrt(3) So x can equal plus or minus the square root of 3
How do you solve 2x2 plus 20x plus 48 equals 0 using the quadratic formula- please show steps?
That factors to 2(x + 4)(x + 6) x = -4, -6
What is x2 plus 7x equals - 2x2 plus 6 in the form ax2 bx c equals 0?
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
X2 plus 20x plus 4 equals 0?
x2 + 20x + 4 = 0 x2 + 20x + 100 = 96 (x + 10)2 = 96 x + 10 = ±961/2 x = -10 ±961/2 x = -10 ±4√6

How do you factor 20x cubed minus 70x squared plus 60x?
20x3 - 70x2 + 60x = 10x(2x2 - 7x + 6) = 10x(2x - 3)(x - 2).
Solution set for 4x2-6 equals 2x2?
Reading this as: 4x2-6=2x2 This implies that: -6=-2x2 3=x2 x=sqrt(3) and x=-sqrt(3) So x can equal plus or minus the square root of 3
What is the answer when you isolate x in 4x2-6 equals 2x2?
x = square root of 3.
2x2 - 3 equals -6x - 2?
2x2 + 6x - 1 = 0 (-6 +/- sqrt (36 - 8)) /4 ( -6 +/- 5.29) / 4 -1.5 +/- 1.32 -2.82 or -0.18
What are the values of X in the equation 2x2 equals 10x plus 12?
2x2 = 10x + 12 2x2 - 10x - 12 = 0 x2 -5x -6 = 0 x2 - 6x + x - 6 = 0 x(x -6) + 1(x -6) = 0 (x+1)(x-6) = 0 x = -1 or x = 6
What does x equal in 2x squared plus 6 equals 30?
2x2 + 6 = 30 is your statement.2x2 = 24x2 = 12x = ±√12x = ±√(4*3)x = 2√3 or x = -2√3
How do solve 2x squared plus 10 equals 58?
To solve for x: 2x2 + 10 = 58 2x2 = 48 x2 = 24 x = √24 x = √4 × √6 x = 2√6
