I need to find the zeros of the function:

f(x)=2x^2-5x-3

Answers

Answer 1

Answer: $2x^2-5x-3=0\n 2x^2-2x-3x-3=0\n 2x(x+1)-3(x+1)=0\n (2x-3)(x+1)=0\n x=(3)/(2) \vee x=-1$

Solve the equation: Show work step by step

-14=-5+3c

Answers

-14 = -5 + 3c

First, regroup your terms. / Your problem should look like: $-14 = 3c - 5$
Second, add 5 to both sides. / Your problem should look like: $-14 + 5 = 3c$
Third, simplify -14 + 5 to -9. / Your problem should look like: $-9 = 3c$
Fourth, divide both sides by 3. / Your problem should look like: $-(9)/(3) = c$
Fifth, simplify the fraction to 3. / Your problem should look like: $-3 = c$
Sixth, switch your sides. / Your problem should look like: $c = -3$

Answer: c = -3

−14=−5+3c

−14=3c−5

Flip the equation.

3c−5=−14

Add 5 to both sides.

3c−5+5=−14+5

3c=−9

Divide both sides by 3.

3c/3=−9/3

c=−3

Point P has coordinates (2,3). Point Q is symmetric to point P with respect to the line x = 4. What are the coordinates of point Q. Im wondering how you solve this. I think it's (3,6) A. (2,5)

Answers

You are given the first point (2, 3) and a line x = 4. If you go ahead and graph these, it makes it a little more clear when they say that point p is symmetric with point Q with respect to the line x = 4.

Line x = 4 is the line of symmetry, so point Q is reflected across it. Point p has an x value of 2 (2 away from the line of symmetry, so point Q's x value has to be 2 away on the other side... 6. The y value is unchanged so your point is
