Question11] $x^{2}+28 x-60$ 12] $x^{2}+7 x-30$

Studdy Solution
Verify the factorization by expanding the binomials:
$$(x + 10)(x - 3) = x^2 - 3x + 10x - 30 = x^2 + 7x - 30$$
The factorization is correct.
The factored forms of the quadratic expressions are: - Problem 11: $(x + 30)(x - 2)$ - Problem 12: $(x + 10)(x - 3)$
