Solve the equation using the distributive property:
(8x+9)(5−x)=31x+94
To solve the equation (8x+9)(5−x)=31x+94, we will use the distributive property. The steps are as follows:
- Step 1: Apply the distributive property to the left-hand side.
We do this by multiplying each term in the first binomial by each term in the second one:
- (8x+9)(5−x)=8x⋅5+8x⋅(−x)+9⋅5+9⋅(−x).
- Simplify the terms:
8x⋅5=40x,
8x⋅(−x)=−8x2,
9⋅5=45,
9⋅(−x)=−9x.
- Combine all like terms:
The left-hand side becomes −8x2+40x+45−9x=−8x2+31x+45.
- Step 2: Compare both sides of the equation:
We have −8x2+31x+45 on the left-hand side and 31x+94 on the right.
- Step 3: Set the equation:
−8x2+31x+45=31x+94.
- Step 4: Subtract 31x from both sides:
−8x2+45=94.
- Step 5: Now subtract 45 from both sides:
−8x2=49.
- Step 6: Divide by −8:
x2=−849.
- Step 7: Evaluate the Result:
The result x2=−849 implies taking the square root of a negative number, which results in an imaginary number, thus indicating no real solution exists.
Therefore, the solution to the equation is: There is no solution to the equation.
There is no solution to the equation.
