expand. your answer should be a polynomial in standard form. $2x^{2}(9x^{2}-16)=$
Answer
Explanation:
Step1: Apply distributive property
$2x^{2}(9x^{2}-16)=2x^{2}\times9x^{2}-2x^{2}\times16$
Step2: Multiply coefficients and add exponents
$2x^{2}\times9x^{2}=18x^{2 + 2}=18x^{4}$, and $2x^{2}\times16 = 32x^{2}$
Answer:
$18x^{4}-32x^{2}$
