5 and 6 have no common factor, ie they are co-prime.
You cannot since the expression does not have rational roots.
You factor out 5 from the expression (10+5p). You get 2(5+p).
2y2(3y - 1)
Look in an advanced maths book.Improved answer:-If the discriminant of the quadratic expression is less than zero then it's not possible to factor it.

2x + 6 = 2(x+3)
14x + 114 = 2(7x + 57)
For each of a list of algebraic expressions, find one or more common factors and factorise the expression.
7 and 4
You factor out 5 from the expression (10+5p). You get 2(5+p).
You cannot since the expression does not have rational roots.
2y2(3y - 1)
Look in an advanced maths book.Improved answer:-If the discriminant of the quadratic expression is less than zero then it's not possible to factor it.
If it does not have a common factor, you cannot factorise it!
It is possible to factorise 4x²-9 further.Factorising is to express a number or expression as a product of factors.The technique of factorising two terms: a² - b² = (a + b) (a - b)If we apply ( 4x²-9 ) to the previous technique: 4x² - 9 = (2x + 3) (2x - 3)
Factorise fully is when brackets are involved in the equation
Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)
