Let's solve your equation step-by-step.x2−7x+12=0

Step 1: Factor left side of equation.(x−3)(x−4)=0

Step 2: Set factors equal to 0.x−3=0 or x−4=0x=3 or x=4

Answer:x=3 or x=4

Good luck mate :P

Answer:

x=3, x=4

Step-by-step explanation:

[tex]x^2-7x+12=0[/tex]

Product is 12 and sum is -7

We need to find out two factors whose product is 12 and sum is -7

-4 times -3 = +12

-4 +-3=-7

[tex]x^2-7x+12=0[/tex]

[tex](x-4)(x-3)=0[/tex]

Set each factor =0 and solve for x

x-4=0 so x=4

x-3=0 so x=3

The value of x is 3 and 4
