Rewrite y = x2 + x - 20 in factorized form.

y = x2 + x - 20 factors into

y = (x +5) * (x -4)

Step-by-step explanation:

y = (x + 5)(x - 4)

Step-by-step explanation:

Given

y = x² + x - 20

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (+ 1)

The factors are + 5 and - 4, since

5 × - 4 = - 20 and 5 - 4 = + 1, thus

x² + x - 20 = (x + 5)(x - 4)
