X squared + 7X + 12?
It is: x(x-3) factorized
x(x - 7)
x(x-7)
7x-x2 = x(7-x)
What about it? Factorise it?
To factorize x^2 + 7x, we look for two numbers that multiply to the constant term (7) and add up to the coefficient of the x term (7). In this case, those numbers are 1 and 6. Therefore, we can rewrite the expression as x^2 + 1x + 6x + 6. Next, we factor by grouping: x(x + 1) + 6(x + 1). Finally, we factor out the common binomial factor of x + 6 to get (x + 1)(x + 6) as the fully factorized form.
x2 + 4x = x(x + 4)
13X squared + 7X + 12
X2 - 4= (x + 2)(x - 2)===========
(x + 2)(x + 1)
x2 - 41 cannot be factorised.
