Hello:
<span> −2x² − 3x + 8
delta = (-3)²-4(-2)(8) =9+64 = 73 ... (delta) </span><span>> 0</span>
The discriminant is 73, so the equation has 2 real solutions
168 is twice 84, whereas 84 is the square of 7*12. Therefore,
168 = 2(84) = 2(2)(42), or 2(2)(2)(3)(7)
The prime factors of 168 are 2^3*3*7.
Answer:
Role of zero and one- 0 is the additive identity for rational numbers. 1 is the multiplicative identity for rational numbers. Multiplicative inverse- If the product of two rational numbers is 1, then they are called multiplicative inverse of each other.
