Simplify the expression.
–x(6x – 7)
A. –6x2 + 7x
B. 5x2 – 6x
C. 6x + 7x
D. –6x – 7x
To simplify –x(6x – 7), we need to use the distributive property, which states that a(b + c) = ab + ac. Applying the distributive property, we get:
–x(6x – 7) = –x × 6x – x × (–7)
= –6x2 + 7x
Therefore, the correct answer is A. –6x2 + 7x.
