Solution for 2x +3 =-4

Step-by-step explanation:

To solve for x...

we have to get x alone on one side of the equation.

we can first subtract 3 from both sides

2x = -4 -3

simplify...

2x = -7

then we can divide both sides by 2

x = -7/2

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
