WebUsing the difference of two squares formula to factor the polynomial Given polynomial 5 x 2 − 45 The difference between two squares is a squared number subtracted from another squared number to get factorized in the form of ( a 2 − b 2) = ( a + b) ( a − b) View the full answer Final answer Previous question Next question WebThe easiest way to solve this is to factor by grouping. To do that, you put parentheses around the first two terms and the second two terms. (x^3 - 4x^2) + (6x - 24). Now we …
Factoring polynomials: common binomial factor - Khan Academy
WebFactoring polynomials can be easy if you understand a few simple steps. This video will explain how to factor a polynomial using the greatest common factor, trinomials and special factoring rules. The process of finding factors of a given value or mathematical expressionis called factorisation. Factors are the integers that are multiplied to produce an original number. For example, the factors of 18 are 2, 3, 6, 9 and 18, such as; 18 = 2 x 9 18 = 2 x 3 x 3 18 = 3 x 6 Similarly, in the case of polynomials, the factors … See more There are six different methods to factorising polynomials. The six methods are as follows: 1. Greatest Common Factor (GCF) 2. … See more There are a certain number of methods by which we can solve polynomials. Let us discuss these methods. See more 1. Factorise: (i) 16x2+ 40xy + 25y2. (ii) x2– ( y – 3)x – 3y 2. Factorise by splitting the middle term: (i) 4x2– 12x + 9 = 0. (ii) 4x2– 4ax + (a2– b2) = 0. 3. Factorise the polynomial: z2– 3z – … See more Question 1: Check whether x+3 is a factor of x3 + 3x2+ 5x +15. Solution: Let x + 3= 0 => x = -3 Now, p(x) = x3 + 3x2+ 5x +15 Let us check the value of this polynomial for x = -3. p(-3) = (-3)3 + 3 (-3)2+ 5(-3) + 15 = -27 + 27 – 15 + … See more trava tv

So x^2 + 9 = 0 gives x^2 = -9, and there is no real number that can be squared to give a negative answer, so we have to go into the imaginary numbers. To get your answer, you need a difference of perfect squares (x^2 - 9). Comment ( 4 votes) Upvote Downvote Flag more trava trava
