8s+6t-(-5s)-2t simplify the expression like terms
Answers
first find the number that has the same variables
=8s - 5s= 3s
6t-2t=4t
the answer is 3s +4t

=-3(-w-u)+-1(-5+w)
=-3(-w-u)+(-1)(-5)+-1w
=-3(-w-u)+5+-w
Distribute
=(-3)(-w)+(-3)(-u)+5+-w
=3w+3u+5+-w
Combine like terms
=3w+3u+5+-w
=(3u)+(3w+-w)+(5)
=3u+2w+5

If 1+8i and 1-8i are the equation's roots, then the quadratic equation is
x² - 2x + 65 = 0.
What is meant by Quadratic equation?
A quadratic equation is written in standard form as y = ax² + bx + c, where a, b, and c are simple numbers. A quadratic equation's factored form is denoted by the expression y = (ax + c) (bx + d), where a, b, c, and d are simple numbers.
Any quadratic problem can be solved using the quadratic formula. The equation is first changed to have the form ax² + bx + c = 0, where a, b, and c are coefficients. After that, we enter these coefficients into the following formula: (-b ± √(b² - 4ac)) / (2a).
If 1+8i and 1-8i are the equation's roots, then:
x - (1 + 8i) = 0 and x - (1 - 8i) = 0 then we get
x - 1 - 8i = 0 and x - 1 + 8i = 0
⇒ (x - 1 - 8i)(x - 1 + 8i) = 0
⇒ x² - x + 8ix - x + 1 - 8i - 8ix + 8i + 64 = 0
⇒ x² - 2x + 65 = 0
The quadratic equation is x² - 2x + 65 = 0.
