6a square plus b square
a(x + y - z)
ax + b = 15 or ax + b = -15
Ax + By = C By = -Ax + C y = (-A/B)x + C/B
It is a straight line with gradient -A/B and intercept C/B.
3a+ax+3b+bx = 3(a+b)+(a+b)x = (a+b)(3+x)
6a square plus b square
x^3 + ax + 3a + 3x^2 = (x^3 + 3x^2) + (ax + 3a) = x^2(x + 3) + a(x + 3) = (x + 3)(x^2 + a)
x3 + ax + 3a + 3x2 = x (x2 + a) + 3 (a + x2) = x (x2 + a) + 3 (x2 + a) = (x2 + a)(x + 3) Checking the work: x3 + ax + 3x2 + 3a or x3 + 3x2 + 3a + ax = x2 (x + 3) + a (3 + x) = x2 (x + 3) + a (x + 3) = (x + 3)(x2 + a)
a(x + y + z)
ax + ay - AZ = a(x + y - z)
a(x + y - z)
Ax + Bx + C is called an algebraic expression.
x2+bx+ax+ab = x2+ax+bx+ab = x(x+a)+b(x+a) = (x+a)(x+b)
AX + BY is not an equation .AX + BY + C = 0is the general equation for a straight line.
ax + b = 15 or ax + b = -15
Ax + By = C By = -Ax + C y = (-A/B)x + C/B
