If you are factoring a quadratic like x^2+5x+4 you want to find two numbers that Add up to 5 Multiply together to get 4 Since 1 and 4 add up to 5 and multiply together to get 4, we can factor it like: (x+1)(x+4) Current calculator limitations ...
Find a pair of numbers that, when added together, equal the coefficient "b" and equal the constant "c" when multiplied together. Those numbers are used to factor the expression. How can you tell if an expression is quadratic? The general form for a quadratic expression is ax^2 + bx +...
The first step in solving a quadratic equation is to expand the equation and, if necessary, resolve any problems with fractions. For example, given the equation 2(x2+3)=8x, expand this by working out the expression 2(x2+3), resulting in 2x2+6=8x. Next, group all terms in the equa...

The product is a quadratic expression. Set equal to zero, x2+x−6=0x2+x−6=0 is a quadratic equation. If we were to factor the equation, we would get back the factors we multiplied. The process of factoring a quadratic equation depends on the leading coefficient, whether it is 1...
Looking at the coefficients of this quadratic expression, I have a = 2, b = 1, and c = −6, so ac = (2)(−6) = −12. This tells me that I need to find factors of −12 that add up to +1. The factor pairs for 12 (not considering signs) are 1 and 12, 2 and 6...
Factoring an algebraic expression: Example 1: Initially, factor $x^2 - 4$ Step 1: See this as a discrepancy of squares. $a^2-b^2=(a+b)(a-b)$ Step 2: Rewrite $x^2 - 4$ as $x^2 - 2^2$. Step 3: Use the formula. $x^2-4^2=(x+2)(x-2)$ ...
