Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
angle of RQS = 45 degrees so
5X-15 = 45
5x=60
x = 12
Like terms: and , and , and
Not like terms: and , and , and
Two or more terms are called like terms if they have same variables and powers.
and are like terms because they have same variable y with same power 2.
and are not like terms because they have same variable y with different powers.
and are like terms because they have same variables kt with same power 1.
and are like terms because both are constant.
and are not like terms because one have variable and other is constant.
and are not like terms because they have different variables.
If two angles are not complementary, then their angles add up to 180 degrees.
