Question

-4x ²-3x+2=0 can you help me solve this

Answer 1

Answer:

x = (-3 ±√41)/8

Step-by-step explanation:

When you match your equation to the form ...

... ax² +bx +c = 0

you can see that ...

• a = -4
• b = -3
• c = 2

These are the values you use in the quadratic formua to find the solutions for x.

... x = (-b ±√(b²-4ac))/(2a) . . . . . . the quadratic formula

... x = (-(-3) ±√((-3)² -4(-4)(2)))/(2(-4)) . . . . fill in a, b, c

... x = (3 ±√(9+32))/(-8) . . . . simplify a bit

... x = (-3 ±√41)/8 . . . . . . put the minus sign in the numerator
