Answer:
The two possible outcomes are 4 and -12, so 4
Step-by-step explanation:
The greatest value of x is 4.
Factorization is when you break a number down into smaller numbers that, multiplied together, give you that original number. When you split a number into its factors or divisors, that's factorization.
Given equation
⇒ [tex]x^{2} +8x-30 = 18[/tex]
⇒ [tex]x^{2} +8x-30-18=0[/tex]
⇒ [tex]x^{2} +8x-48=0[/tex]
⇒ [tex]x^{2} +12x-4x-48=0[/tex]
⇒ [tex]x(x+12)-4(x+12)=0[/tex]
⇒ [tex](x+12)(x-4)=0[/tex]
x = -12 and x = 4
Hence, the greatest value of x is 4.
