Answer:

First option:  3x^2-5x=-8

Second option: 2x^2=6x-5

Fourth option: -x^2-10x=34

Step-by-step explanation:

Rewrite each equation in the form ax^2+bx+c=0 and then use the Discriminant formula for each equation. This is:

D=b^2-4ac

1) For 3x^2-5x=-8:

 3x^2-5x+8=0

Then:

D=(-5)^2-4(3)(8)=-71

Since D this equation has no real solutions, but has two complex solutions.

2) For 2x^2=6x-5:

 2x^2-6x+5=0

Then:

D=(-6)^2-4(2)(5)=-4

Since D this equation has no real solutions, but has two complex solutions.

3) For 12x=9x^2+4:

 9x^2-12x+4=0

Then:

D=(-12)^2-4(9)(4)=0

Since D=0 this equation has one real solution.

4) For -x^2-10x=34:

 -x^2-10x-34=0

Then:

D=(-10)^2-4(-1)(-34)=-36

Since D, this equation has no real solutions, but has two complex solutions.

Can someone help me with this question.
Korolek [52]

Answer:

lesser x = -4

greater x = 1

Step-by-step explanation:

here's the solution :-

=》

{x}^{2}  + 3x - 4 = 0

=》

{x}^{2}  + 4x - x - 4

=》

x(x + 4) - 1(x + 4)

=》

(x + 4)(x - 1)

now, there are two cases

case 1) where x + 4 = 0

=》x = -4

case 2) where x - 1 = 0

=》x = 1
