The solutions are: x = −4,x = 7 Explanation: X^2−3x−28= 0 We can first factorise this expression by splitting the middle term and then find the solutions: = x^2−7x+4x−28=0
= x( x−7) + 4( x − 7)=0 =(x+4)(x−7) Now, we can equate the two factors with zero and find the solutions: x+4=0,x =−4x−7=0,x=7
Answer: 10^3 Step-by-step explanation: any time you see a number for example 7^6 you always start with those first when you have a math question like the one on the screenshot
