Answer:
1) A
2) D
3) 49
4) (Solve)
: 2x^2-5x+6
: x^2+2x-5
Step-by-step explanation:
1) The answer is A because of the roots that come from the factored equation. A becomes factored in to (x-1)(x-2), so the roots are x-1=0, and x-2=0.
2) I think the answer for this has to mostly be D, because of the square root of x included in the bx term. I am not fully sure of this so please forgive me if it is wrong.
3) The discriminant is b^2-4ac, so a=1, b=5, and c=-6. If you put in, you get 5^2-4(1)(6), which is 25+24=49.
4) Remember that you need to have everything in the form of ax^2+bx+c, so for (1) you subtract 5x and and add 6 on both sides. For (2) you distribute the x into (x+2), which gives you x^2+2x, and then subtract 5.
I hope this helped!! PLEASE PLEASE mark brainliest, rate, and give thanks!!
Answer:
Step-by-step explanation:In (1)
Option (A) is correct because alpha + beta= -(-3)/1.
(2) option (D) is the answer.
(3)49 is the answer. By applying b^2-4ac we got that.
(5) (1) 2x^2-5x+6=0
(2) x^2+2x-5=0
