Expand π¦ times π¦ plus four.
00:00:04.960 --> 00:00:05.960
Circle your answer.
00:00:07.600 --> 00:00:17.480
When we look at this expression, π¦ and then brackets around π¦ plus four, thereβs an operation happening between the π¦ and the brackets.
00:00:18.800 --> 00:00:21.920
π¦ is being multiplied by π¦ plus four.
00:00:22.760 --> 00:00:30.360
In order to expand this expression, we need to multiply π¦ by both terms inside the brackets.
00:00:31.760 --> 00:00:36.960
First, we would say π¦ times π¦ plus π¦ times four.
00:00:37.800 --> 00:00:43.080
π¦ times itself equals π¦ squared, and four times π¦ we rewrite as four π¦.
00:00:43.080 --> 00:00:47.680
The expanded form is π¦ squared plus four π¦.
00:00:47.680 --> 00:00:53.600
We can also plug this expression into a grid: π¦ times π¦ plus four.
00:00:54.240 --> 00:01:03.040
π¦ times π¦ equals π¦ squared, and π¦ times four equals four π¦.
00:01:03.880 --> 00:01:08.040
And the grid method yields the same result, π¦ squared plus four π¦.
