Question and answer
What are the coordinates of the vertex of the graph of the given function? y=-4x^2+3
The coordinates of the vertex of the graph of the given function y=-4x^2+3 is ( 0 , 3 ) when x = 0 , y is the largest when x = 0 , y = -4*0^2 + 3 = 3 so the coordinates of the vertex is ( 0 , 3 ) .

when x = 0 , y = -4*0^2 + 3 = 3
so the coordinates of the vertex is ( 0 , 3 ) .

Solve by factoring. 2x^2-5x=12
Question

1 Answer/Comment
2x^2 - 5x = 12;
2x^2 - 5x - 12 = 0;
(2x + 3)(x - 4) = 0;
2x + 3 = 0; 2x = -3; x = -3/2;
x - 4 = 0; x = 4

x = -3/2 or x = 4

Solve by factoring. 4a^2-4a=15
Weegy: 4a^2 - 4a = 15; 4a^2 - 4a - 15 = 0; (2a + 3)(2a - 5) = 0; 2a + 3 = 0; 2a = -3; a = -3/2; 2a - 5 = 0; 2a = 5; a = 5/2 a = -3/2 or 5/2 (More)

The solution for d^2 - 4 - 96 = 0 is d = 12 ,or d = -8 .
d^2 - 4d - 96 = 0
(d - 2)^2 - 4 - 96 = 0
(d - 2)^2 = 100
d - 2 = 10
d = 12
or
d - 2 = -10
d = -8

6x^2 + 77x = 13
6x^2 + 77x - 12 = 0
a = 6 , b = 77 , c = -12
