Solve for x, give exact answers: 6x^2 - 7x - 3 = 0
Novosadov [1.4K]

Answer:

Step-by-step explanation:

6x∧2-7x-3=0

the coefficient of x² multiplied by -3 = -18

we need to look for 2 numbers that when we add it to together it will equate to -7x

+2 and -9 is the answer

6x∧2+2x-9x-3=0

2x(3x+1)-3(3x+1)=0

(2x-3)(3x+1)=0

equate each brackets to 0

2x-3=0   3x+1=0

2x=3        3x=-1

x=3/2         x=-1/3
