Factor the equation 3x² +5x-2 by breaking down the 5x term into the sum of two terms, ax and bx. You choose a and b so that they add up to 5 and when multiplied together give the same product as the product of the coefficients of the first and last term of the equation 3x...
Quadratics are the polynomial equation which has highest degree of 2. Also, called quadratic equations. Learn quadratic formulas, solution to quadratic equations with the example at BYJU'S.
You're left with (x - 1/3) (3) (1x^2 + 3x + 2). Factor out the trinomial via the quadratic equation (this equation was used as an example in step [6], so refer back if you need to). You'll end up with (3) (x - 1/3) (x - ((-3 + sqrt 17)/2)) (x - ((-...

these methods, we can factorise the polynomials by the use of general algebraic identities . similarly, if the polynomial is of a quadratic expression, we can use the quadratic equation to find the roots/factor of a given expression. the formula to find the factors of the quadratic expression...
To factor a quadratic, it's really nice not having a negative x2 term, so let's divide that part out first. Pulling a negative from each term leaves us with this equation instead. Now we can begin to look for the two numbers that have a product of -16 and a sum of -6. The re...
If I factor it out into two separate terms, I find that (x+2)(x-1) is the same thing as x^2 + x-2, so I can factor this quadratic as (x+2)(x-1). Once I've factored the bottom, I know that I can rewrite this entire equation as being equal to A/(x+2) + B/...
