(x + 8)(x + 2)
x2+6x+9 = x+3 x2+6x-x+9-3 = 0 x2+5x+6 = 0 Solve by factoring or with the help of the quadratic equation formula: (x+3)(x+2) = 0 Therefore: x = -3 or x = -2
The roots are -3 and -7. Easily by factoring and setting each factor equal to 0. The factors are x + 7 and x +3.
x2 + x2 + x2 = (1 + 1 + 1)x2 = 3x2
-(x - 1)(x2 + x + 1)
x2 + 5xy - 18y2 can not be factored.
(x + 8)(x + 2)
x2 - 14x + 49 = (x - 7)2
(x+8)^2=105
An equation would be....,X2 - 10X + 16 = 0easy factoring(X - 2)(X - 8)==========So.X = 2====
35 + 40x + 5x2 = 5(7 + 8x + x2) = 5(7 + x)(1 + x)
x2+6x+9 = x+3 x2+6x-x+9-3 = 0 x2+5x+6 = 0 Solve by factoring or with the help of the quadratic equation formula: (x+3)(x+2) = 0 Therefore: x = -3 or x = -2
x2-64 = (x-8)(x+8)
y=b+x+x^2 This is a quadratic equation. The graph is a parabola. The quadratic equation formula or factoring can be used to solve this.
This can be factored as (x+3)(x+2). (To do this factoring, in this case you look for two numbers that, when multiplied, give 6, and when added, give 5.)
The roots are -3 and -7. Easily by factoring and setting each factor equal to 0. The factors are x + 7 and x +3.
When the co-efficient of x2 is 1
