You factorise the quadratic expression x²+ (a+b) x +ab by rewriting it as the product of two binomials (x+a) X (x+b). By letting (a+b)=c and (ab)=d, you can recognize the familiar form of the quadratic equation x²+ cx+d. Factoring is the process of reverse multiplicat...

Step 1: SubstituteLet y=x2. Then, the expression becomes:y2+3y−28 Step 2: Factor the QuadraticNow we need to factor the quadratic y2+3y−28. We look for two numbers that multiply to −28 (the constant term) and add up to 3 (the coefficient of y). The numbers 7 and −...
To factorize the quadratic expression of the form ax2+bx+c, splitting the middle term is one of the methods that can be applied. According to the splitting the middle method, we have to find two numbers d and e such that these two numbers satisfy these two conditions b=d+e and ac=de...
Well I do have a advice for you.Sometime back even I was stuck on questions relating to factorise quadratic equation calculator, that’s when my younger sister suggested that I should try Algebrator. It didn’t just solve all my queries, but it also explained those answers in a very nice...
