Step-by-step explanation:
Answer:
3x^2 + 10x - 8 = 0.
Step-by-step explanation:
In factor form it would be:
(x + 4)(3x - 2) = 0 (because x + 4 = 0 gives x = -4 and 3x - 2 = 0 gives x = 2/3);
Now change to standard form:
= 3x^2 - 2x + 12x - 8 =0
= 3x^2 + 10x - 8 = 0.
<span>3x2(7x2 − 9)
Multiply 3x^2 by 7x^2 and -9(Use distributive property)
Final Answer: D.) 21x^4 - 27x^2</span>
