-3x^2+6x+1=4 find the discriminant of each quadratic equation then state the number and type solutions

Discriminant = 0;  1 real root

Step-by-step explanation:

-3x²+6x+1=4  (subtract 4 from each side)

-3x²+6x+1 - 4 = 0

-3x²+6x-3 = 0  (factorize 3 out of the left side)

3(-x²+2x-1) = 0

-x²+2x-1 = 0

Recall that for a quadratic equation in the form:

Ax² + Bx + C = 0, the discriminant = B²-4AC

in our case, A = -1, B = 2, = -1

discriminant = B²-4AC

= 2² - 4 (-1)(-1)

= 4 - 4(1)

= 4 - 4

= 0

Recall that when discriminant = 0, the quadratic equation has 1 real root. (answer)

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
