Question

x²–5x+6
Simplify : x²+x-12
22-x-2
22+5x+4​

Answer 1

Answer:

x²–5x+6=(x-3)(x-2)

x²+x-12=(x+4)(X-3)

22-x-2=x=20

22+5x+4=x=-26/5

Step-by-step explanation:

x²–5x+6

• x²-3x-2x+6
• x(x-3)-2(x-3)
• (x-2)(x-3) is the answer

x²+x-12

• x²+4x-3x-12
• x(x+4)-3(x+4)
• (x+4)(X-3) is the answer

22-x-2

• 22-2=x
• x=20 is the answer

22+5x+4​

• 26=-5x
• x=-26/5 is the answer
